I hold onto the stock coolers. I'm not sure why, but I do. I have a box just for old heatsinks and fans.

An Intel stock cooler for a 65 watt CPU might be excellent if it could be mounted on a 20 watt CPU. I'm in favor of repurposing NOS items.

Yeah I always figure I might be able to use them on another project sometime. I have a heatsink at work I rest my phone on while charging to help dissipate the heat. Then some of my old stock P4 heatsinks I am thinking of using on a solar panel inverter I'm designing.

There is a line on SIV64 across from L1 Data Cache that says 47C. I think that is the temp on the reverse side of the MB behind the CPU. I guess that would be the number I should always check. Right? Rather than the cpu core #'s.

[quote]Hal,
What scared me more than anything was your saying you had to replace 2 mb's before you discovered it was the cpu. No thanks - too much work for me.

I went through so many sets of memory & MBs because I didn't even consider it was the CPU. As memory & MB issues are infinitely more common than an actual faulty CPU.

Despite building my own computers for a few decades & never having such an issue before. I am still not 100% sure that I didn't do something to cause the issue I was having with the CPU. That seems more likely to me than a failed chip getting though multiple quality screenings, or there being a faulty batch due to failed test equipment.

I'm not sure what the value in SIV is as I don't use it to monitor my temps. It could very well be the external CPU temp. To me 47ºC seems like a reasonable temp to be reading.
With my thermostat telling me it is 75ºF in the living room. My HTPC with an i5-4670K is reading:
49ºC external CPU temp
57-58ºC core temps
34ºC MB/case temp
39ºC PCH (chipset) temp

All of the values are good to monitor. I focus more on the CPU core temps rather than the external temp. As the core temps are really the important part. It doesn't matter how cool the outside of the CPU is if the cores are melting. If you are reading 20ºC for the external CPU temp, but the cores are at 95ºC you are probably going to have a bad time.

However, despite the claims about how Arctic Silver 5 "never dries out" are in fact wrong. I took a heatsink off of my Athlon XP 3200+ machine about a year ago. I applied AS5 to it in 2005 right after I got the AS5. When I released the latches on the heatsink..the CPU came out of the socket with the heatsink. I twisted and pried and almost broke that delicate little Barton in the process, but it finally got released. The AS5 had dried out and become epoxy, basically.

So... moral of the story is.. replace your thermal compound every 2-3 years.

I have had the CPU come out with the heatsink a few times in the past. I found running the CPU hard to heat it up would normally reduce the chances of that occurring.

I hate to keep throwing away these little tubes of thermal paste but I have no idea what their shelf life is. Anybody know?

Not sure. Given it is a sealed tube I imagine it should say good for quite some time. The oldest I have is around 5 or 6 years old & I was just using it to regoop an old P4 heatsink recently.

Hmm, AP WU's from 2014 tapes seems to be extremely noisy, at least those I have crunched today (unfortunately with totally new settings for today on the GPU).

A majority of all the ones I have crunched so far today, have a very high pulse count.

Since many of them are still waiting for a wingman, I do not know if there's an issue with my GPU, or if they really are that noisy.

Time will tell I guess....

I have been seeing a large volume of high pulses and blanking recently.

If I had known that I may have kept with the quieter intel HSF. I cleaned the intel off and put it in the drawer for possible use here or in my old dell which also has an intel HSF and has done a good job for about 5 years now.

I know something else. It's easier to get paste off that is only a week old than paste that is 4 years old. Alcohol is great!

Here's to ya.

I just use paper towels and rub the gunk off until it comes back clean.

I hold onto the stock coolers. I'm not sure why, but I do. I have a box just for old heatsinks and fans.

Thanks Ivan,

I just installed my cooler master. The temps went from (today) 79-86C to 58-68C.
Wow! Thanks everybody.

The noise. Well it is a bit louder but not as bad as the old rig so I can live with it.

Shame on intel for not putting a big black and yellow sticker attached to that fan and cooler explaining what is what. People putting together a rig without the benefit of a group like this are gonna make big mistakes. [Even the ones with common sense]

The stock heatsink is more than adequate probably around 99.5% of machines.

Much like system in your car. If you were to load it up to its maximum load weight & then drive at full speed. You would then find the limits of its cooling capacity fairly quickly. Most people never do that. Do the factory cooling system is designed for most normal use cases. Then the aftermarket takes over for those with higher demands.

Anyone else experience a slow down of the servers? I managed to report, after a few of these:


563 SETI@home 2014-10-24 03:42 Reporting 1 completed tasks, requesting new tasks for CPU and GPU
564 2014-10-24 03:42 Project communication failed: attempting access to reference site

566 2014-10-24 03:42 Internet access OK - project servers may be temporarily down.

Looking over the longs on my 6 home boxen & my Android. I don't see any connection issues for the the past 5 hours other than my one notebook that drops its wifi connection sometimes.

I can't stop laughing. It's such a visual!

Zalster,
The only reason is so that intel can't point the finger at cooler master or some other mfg. of the heatsink/fan. Also, right now the intel heatsink/fan is running very quietly and that was my chief complaint on my prior rig but that may have involved other factors (MB,bios,etc).

I would install that cool master, My CPU never gets over 45C supporting my 3 GPUs running full out. Why would you want to risk burning out that chip? If it runs cooler, less chance of something going wrong. My 2 cents...

Zalster

So long as you don't do something like physically beat the CPU to death with a hammer I don't expect you would have any issues replacing it under warranty. When I had to replace my i5 I didn't mention I was using an aftermarket cooler & they didn't ask.
If you completely crazy overvolting the CPU when overclocking you might be able to kill it. I have some CPUs I have actually tried to kill through overclocking & they are still living despite my efforts. :/ It makes me sad when I can't break something. As I am a Test Engineer for a living. So I get paid to break things. Mostly software/firmware, but also a hardware when the need arises.

If you watch Game of Thrones this might be entertaining to you.

The intel i7 4790K runs hot from 75-85C. using 7 cores and part of a core for the cpu. The ambient room temp is 68F. I bought the boxed intel with the intel fan and heatsink which implies to me that if I use their heatsink and fan I should be covered under the warranty for 3 years. In reading the warranty it looks like I should be covered.

I have I higher priced cooler master but did not install it.


I assume that if I don't overclock and use intel's fan and heatsink I am covered under their warranty. Any comments.

Is the the temperature of the cores or the case temp? If that is the case temp that seems high. Even for a stock Intel cooler. If it is the temp of the cores then it isn't to bad.

The K edition processors support overclocking from the factory. That is the extra $ you pay vs the non K editions.
The Intel warranty support process is pretty easy. "Hey Intel this isn't working & is under warranty" "OK do you want a standard replacement or advanced replacement?". I had to have one of my i5-4670K CPUs replaced when it wouldn't boot with memory in the 2nd channel on the MB. I has gone through 3 MBs & 4 sets of RAM before contacting Intel for a CPU replacment.

Maybe,
The installer replaces any existing ap_info.xml with one of its own, you will need to re-modify the ap_info.xml to your parameters.

Regards,

OR just use an app_config.xml to set your number of tasks per GPU so you don't have to mess with your app_info.xml & your settings don't get changed when you rerun the installer.

Thanks for the update & to Angela for putting up all of the extra time you put in.

Got to love those "This should be quick" moments that turn out to takes ages.

Have you guys noticed AP workunit assimilation, and by extension purging, hasn't been occurring for a while? Wasn't sure if it was intentional or if something just went a little wonky after the validation wasn't occurring previously.

Something is afoot. One of my machines hasn't been able to connect to the server all day. I keep getting "site might be down" I know the internet works because I'm using the computer right now. Wonder if something broke that they couldn't fix so the put the system back up until they would get whatever it is they need or the appropriate personnel to look at it. It's also super slow and certain sections take several minutes to load

The connection connection graph also shows that is normally the outbound data, labeled as in, running around 25-30MB/s. With the outbound, labeled as out, running around 240MB/s. For a moment I thought they reversed the display, but I'm thinking not. As the "Results ready to send" has also stayed extremely flat.
Looking at my clients I just have the standard messages that would be expected after an outage.

Something wrong I guess.

Not having any issues on this end... well anymore. My internet went from 25Mb/s to about 18Kb/s for around an hour. So there could be some kind of larger internet issues occurring.

Well, after having done 189 non-outlier tasks, (Consecutive valid tasks 306), the credits for AP v7, haven't even come close to that of AP v6. It's rising slowly though, but is still not consistently at even 500 Credits.

Patience young man, patience....:-)

Edit, added: We've been running the new AP v7 now since October 9th, and still no official announcement of this new app on the board. Who stole the keyboards of the SETI project admins?

I have just seen the average graph in my BOINC Manager start to move upward. With the 19th the lowest point. Also the lowest credit I am seeing granted for a non blanked AP task is around 515.
