Titanium too. Good choice.

That means, when future archaeologists, evolved from whatever inherits our world, go looking through the fossilized remains of our society, they will find our titanium watches you and I; even if nothing remains of our bones. My titanium watch is not nearly so fancy, but its body and bracelet will also outlast me by aeons. I've had it for many years, and it has withstood the test of time so far in pristine condition.

Go for it.

My radiator does indeed sit at the top, and pulls in air just as you describe. It is the meat in a fan sandwich. The PSU also has a 120mm fan drawing internal warm air past its own heat producing gubbins, and exiting to the rear. Chassis fans front and rear pull and push the air in the appropriate front to rear direction, giving excellent air flow. Several side vents allow pressure equalisation. I believe the fact that my GPU temp has also dropped, shows that the cooling system works exactly as it is supposed to.

I'm afraid actual experience tends to disprove the theory that I should be attempting to cool the CPU with pre-warmed air. My rig works. Short of the lottery win, this is as good as it gets for my money.

Cooling the CPU's heat output, in this case my only real aim, is best done with ambient air, rather than air pre-heated by the GPU & chipsets. It is what Corsair recommends, and when you really understand why, it makes sense. With the air cooled fan blowing it all out to the GPU it was not exactly a Great idea before. This way my GPU is actually running slightly cooler too as an added bonus.

Mark is right, in that having the whole shebang outside the case would be a better , if uglier option. But for that I would be building something for a purpose to which I don't put my PC.

If I needed to go that far, I would have built a whole system from scratch, radiator outside, with a nice large reservoir that also had cooling fins. I would have had a separate pump, large enough to add multiple GPU heads (called blocks to some?) and chipset heads too. It would probably use a large aquarium tank as a heat sink too, so the reservoir would actually sit inside the aquarium filter/pump assembly to act as an aquarium heater. It would also sit inside the new house that I had purpose built for me just after I won the lottery.

Well, its up and running. Very quietly compared to the old air cooling setup too.

I went with full power Push and the CPU controlled Stock Corsair pulling. Sucking in ambient air through the radiator. Lots of quiet expelling fans giving a good air flow. Improved airflow has even made the GPU marginally cooler.

100% usage on full voltage gives me a transient peak high of 48°c on CPU 0, the other four cores are under 45°c peaking at 46°c. Compare that to well over 75°c on stock air cooling. I have achieved the desired 30 degree drop. I am happy.

Idle temp does not appear to go below 37-38°c, which is also the sustained temp on its usual daytime diet of low voltage and S@H.

Thanks to everyone who commented. It was great to hear all sides to the discussion. I did listen to all the arguments before deciding. I have no idea whether the stock fan alone would have achieved the same result, because I never tried it on its own. I know the H60 pump and head is the same as the H80. The difference is only a 240 x 120mm rad with two 120 mm fans. I'm not overclocking, I just wanted to have it remain cool under full usage, and I have achieved that. Now I can come home and fire up whatever I want without worrying about snoozing S@H. Everybody wins.

Thank guys. Great feedback so far.

The board's CPU fan plug does control speed. The CPU does crunch, as does the GPU. I simply underclock most of the day. So the whole system is hobbled by reduced CPU voltage I believe. (Electrickery is not my strong point.) This also reduces fan speed on all the boards's chassis and accessory fan sockets.

When I want to use my machine for me, as well as S@H I turn up the speed to full. Then, S@H still takes whatever I am not using, so the CPU is running 100% on standard voltage. It is then that the heat goes up. It also usually means S@H gets marginally more CPU crunching done, but less GPU as the old GPU is not up to working for both of us.

If I read what has been contributed so far, a Y plug will allow both fans to work on a single plug. My spate 120 is not a matched fan, and the only reason to consider it is that I have it, so could use it.

I am still tempted to use the additional fan as an always on full power pusher and the stock fan as a puller. If the always on cools the CPU too much during restricted use, the worst that can happen is that ir reaches ambient temperature right?

Well, maybe not just overclockers, because I am not actually overclocking.

I am rebuilding my everyday box. It has a Q9550 CPU (Core2Quad 2.83GHz). No real fancy GPU, just a NVIDIA GeForce 8500 GT (1023MB)and I specifically don't want a fancier GPU because the machine spends most of the day watching the security cameras for motion. If I get a better GPU it will start thinking something moved if someone in London turns a light on. Its already too sensitive and takes a picture if the sun comes out anywhere in England. OK, so I'm exaggerating, but its already too sensitive.

Anyway, the upshot is that the GPU is not a heating issue.

Now the CPU, with stock cooler fan, doesn't really like it if its on 100% at full voltage for too long. It starts getting hot. (Over 70°c I consider too hot.) So I have got a Corsair H60 liquid cooler for it. I can see the logic in having ambient air pulled through the radiator, and intend to have lots of expelling to compensate. I have a spare 120cm fan. Now for the question for those with a better mind, experience and know-how.

If I use the additional fan to create a push-me-pull-me flow through the radiator I am unlikely to get an exact match on pressure/flow rate. The kit's cooler fan will be plugged into the motherboard's CPU fan socket, and so its speed will vary with the CPU demand. However the other really can't really go in the same socket. So.

    Do I put the constant full power fan as the push or the pull fan?
    Do I bother adding another fan at all?
    Do I put the additional fan through a 'dimmer switch' and attempt to synch them manually when I turn on full power.
    Do I plug both fans into the same socket by splicing the wires?


The ASUS P5K-E board comes with a nice 'underclocking' utility which I use to turn things right down during the hours when the unit is simply guarding the house and spending all idle ticks crunching for S@H.

Suggestions please.

Are there some posts missing here?
I was looking for my post to find out how much I now owe, but can't find it. Looks like the replies only date back from January.

[Edit]
I found 'em. I owe £25. I shall get it paid at the weekend.

After the 1st post it says:

Claggy

Yeah, I saw that after I'd given up looking for my first post. I can only claim to be in the middle of a Fibromyalgia flare up, so last night was either pain or prescription analgesics. I don't remember which, but either one accounts for my lack of concentration. Today is the same. Right now its the analgesics, so I can't work today, but at least I am feeling no pain.

I should really take this machine apart and remove dust bunnies as the temps are running slightly high, meaning I have to leave the CPU on 'high performance' instead of 'max performance'. However the opiates leave me with CBA. (Thats 'Can't Be Arsed' for those who didn't know.) ;)

Probably unwise to tinker with things that involve electrickery in my current condition anyway.

So its not only your bad habits that have to be changed.


Keep going Mark there's a whole lot of us out here who are backing you up.

Indeed it is not just the bad habits.

This:
Relax on the couch after a nice meal........shaZaaaaaam.......have a few beers.......shaZaaaaaaam.......whap, whop, who's your daddy?

Tells you that it is the normal everyday habits that trigger the craving. They are the things that give the other dragon strength. Breaking ALL your habits at once involves 'No couch after a nice meal; No 'few beers'. Those are the triggers. The bell that makes the dog salivate.

Why give the dragon attacks of opportunity? The water routine does more than the flushing and scrubbing away of nicotine. It also replaces many of the habits with a new routine, which helps attack both Dragons at once.

All the best of luck Mark. I really am rooting for you. ... and anyone else your lead inspires to follow suit.

Cangrats, hang in there & welcome back!

Forums just weren't the same without you...

Yeah, and I just wasn't the same without y'all either........or them dang cigs......

Somebody......when does the craving go away???????????
Still has me tearing my hair out and I don't know how long I can endure it.
I did go to the gas stations today, filled up...got a half tank of gas, can of coffee, powereball ticket, and he had my usual pack of cigs on the counter............OMG......I said NO.........got a bit of a puzzled look after all these years, but drove away with another handful of cash in my hand.......LOLouch.

Your post here tells you, if you listen, when the craving will go away.
Currently you are not an ex-smoker, but someone trying to give up cigarettes.

Its two things:
    Physically, once you have flushed the nicotine from your body the physical craving will go.
    Mentally, you have to make the change of habit from being someone trying to give up smoking, to being an ex-smoker. That takes more determination than starting the "trying to give up" phase.


The fact that you ordered your pack before you had realised tells me, and should tell you, that you are still running on the same habit, and are constantly fighting against your own Pavlovian responses.
You know full well that when you go to the gas station you buy a pack, and that habit is still in your head. Change your habits, and get the nicotine out of your system. Then, and only then will you join the ranks of us ex-smokers.

You appear to have taken the harder road because the easier road I told you about in a post above looked too hard at first glance. However you can still do it your way, most people do.

When people use nicotine patches or gum, they are using them to allay the physical craving while they deal with the mental task of becoming a non-smoker. Once they have mastered that, they then have to deal with the nicotine habit that they still have. It is a very long, drawn out, two stage process.

Since they have by that time hopefully, conquered the mental dragon, the physical dragon is less fearsome. However defeating both dragons at once is only one single fight, and you can use one dragon to help defeat the other, so it can be over more quickly. It really does make some sense, even proverbially.

It's been a long time since that's been done well !!
Same thing for the Virgin Birth !!

Parthenogenesis happens all the time. Just not usually in primates like us.

Who is to say whether it happens to ET? It may be normal reproductive behaviour. If the folks writing a couple of thousand years ago had known how common it was in other species, it might not have seemed such a magical/miraculous occurrence.

As there are only 63 stars within 50 light years of earth, 1500 planets would mean some stars would have a lot of them.

Steve

Are we really sure about the low figure of 63?

Having not spent any time counting them myself, I am loathe to state anything as fact; but a quick search of previous counts and estimates from scientific sources places the 1500 figure on the conservative side. 1600 to over 2000 being the predominant range that I found.

Len


I have this.

Hmm. I have three apples and four oranges. However there are seven pieces of fruit. If one were to re-define fruit as "non-citrus fruit", then my statement that I had seven fruits would be wrong by the new definition of fruit, but where would that leave apples? Are they no longer fruit?.

The original poster mentioned "stars". Not spectral type "G" stars. Of those there appears to be 64, granted. But the limit as to a specific spectral type was never given by the original poster.

A planet is a body that orbits the Sun, is massive enough for its own gravity to make it round, and has "cleared its neighbourhood" of smaller objects around its orbit. If we were to substitute "the sun" with "its star", I think we have a working definition of planet, surely?

I disagree Chris. The step-down method doesn't work for EVERYONE. I stopped 10 years ago cold-turkey-never smoked again.

When Sattler has been completely smoke free for 6 months straight, I will give as part of this fundraiser.

I didn't want to be quite that harsh on the man. However, Mark, you now have at least some incentive to prove to us ex-smokers that you can do it.

I too simply stopped smoking. In the '70s I was in training and assisted at two post mortems of road accident victims. One was a smoker, one was a non-smoker; both from a rural area. Their lungs were totally different looking organs. One had pink lungs the other grey. - It was not smoking that killed either of them. That was just the state of their lungs.

I gave up very shortly after that. I went from 30-40 a day to none.

I used a method based on ridding the body of nicotine AND breaking all my habits at once, then selectively taking up only those I wished to continue with. It took two weeks.

First, realise that most of your smoking is habit. So is coffee, tea, carbonated caffeine drinks, alcohol, sitting in your favourite chair after meals, and all the other things that you do by habit. Prepare to stop doing them all for two weeks. After two weeks you can take up whatever other habits you want to.

Then, to rid the body of nicotine, realise that nicotine is slightly soluble in water, and use water to flush it out.
Water on the inside.
Drink only water, and drink more than you need. This will help flush out the nicotine. (which must go to stop the cravings) It will also help make you feel fuller before meals to drink a large glass of water about 5 minutes before the meal. This will help prevent the weight gain that often accompanies smoking cessation.
Water on the outside.
Make a ritual out of this:
    On the first day, when you wash, use ice-water to thoroughly scrub your hands. Then continue to wash all over normally. Preferably multiple times a day.
    Next day, use ice-water to thoroughly scrub up to the elbows. Then continue as the previous day.
    Next day, the whole arms.
    Then the arms and feet;
    arms and lower legs;
    arms and whole legs;
    arms, legs and face/head;
    arms, legs, head, upper torso;
    whole body.


This will take nine days.
Next:
By now, you are thoroughly scrubbed, you have not smoked for well over a week, you have flushed your insides with water.

On the tenth day get a clean, preferably new white towel. Take a sauna if possible, if not get yourself hot and sweaty somehow. Then thoroughly rub yourself down with the clean white towel. Then, and only then, put the towel to your face and breathe deeply through your nose. - The towel smells like an ash tray right? - You need to wash that off your body, right now!

This should allow you to push on through to your goal.

If you find you have to cheat, cheat with the alcohol, coffee, tea, or something that you intend to take up again anyway. (For me, this was coffee, which I have since cut out.) Do not cheat with the tobacco.

Be prepared to catch a few coughs and colds for a while. The smoke has not only been killing you, but helping to kill everything you came in contact with. Including infections. Eventually, your system will no longer rely on a film of tar and poisons to keep it 'safe' from infections. Your body will start to use its own defences like the rest of us.
