Message 1361083 - Posted: 25 Apr 2013, 15:43:27 UTC

Hi guys my new quad cpu is running temps of
core 1 64c
core 2 53c
core 3 58c
core 4 58c
give or take +- 2c
Could anybody that has a quad tell me if these temps are about right as i'm a little worried I mite not have used enough thermal paste or I have not got the heat sink and fan perfectly seated .The quad is a q8400 and the Tcase temp according to intel is 71.4c
I'm prob worrying over nothing so any advice much appericated

Worrying over nothing.
Worry if:
- It goes over 80C (need cleanning).
- A fan stop working.

My I7 920 is running 53 52 51 53 across the cores. My I7 3770 is running 55 54 51 52

Over 70c and I would be getting a little concerned

I'd be concerned if the CPU is not under a load. An Idle CPU shouldn't get into the mid 40's. I assume you are using a stock HSF.

If you are concerned about the seating, try gently turning the HSF(power off of course) and see if it feels like its stuck in mud. You should get a bit of movement(a few mm side to side) but it should be fill like its stuck in mud

You should be fine with those temps (if that's under full load) and that CPU will start throttling at around 75C anyway, then shut itself down if it necessary.

What HSF are you using on it?

Cheers.

Sorry no answer straight way was late and crashed

I'm not shore it's name the HSF but the fan is Intell and the heat sink is about 2 x thicker than a normal sink
during the day it's been pushing 66-68 and it's only 1 core that is getting that high the others are about up to 7c lower .
I could not find at intel what temp it burns out only the Tcase 71.4
Wiggo you say it will start throttling at 75 ?? if 75 I can relax

The HSF is intel I believe but not standard I had to hunt around to get it this thick

Less is better. If too much thermal compound is applied, it will work as an insulator, so less heat will be transferred.
TC is used to smoothen both surfaces because they are not perfectly flat.

It seems to be ok it's only getting to 67c and that's in the hottest part of the day still getting to 25c and winter on it's way
I only used about harf the TC in the seringe but thank mate

MM ok then I have used to much I used about the size if a 5c coin (I think your eqivelent is a dime ) and I used mk2 same as you .I better get more and redo it and hopefully the Temp will go down .
When she is idling it's about 42c the hottest core which I did think was to hot seeing as it has a extra think heat sink . I been expecting it to get a cooler
at night as the temp has been dropping to about 14c but it only drops 2-3 c.
Thank Mark i'm going back to market to exchange the ram as he gave me ram that was too fast for the chip I needed 667mhz he gave me 800 so i'll buy some more TC and do it again.
Good timing mate thanks

My i7-2600k is around that temperature at idle, when the ambient temperature is in the mid 30°s, so yeah, it's way too hot.

Been years since i had to refit a heatsink, but i've always done it similary to what msattler said. I'm smear a thin coating of heatsink paste on the CPU & then use a a small piece of plastic with a straight edge (old credit cards are usefull for something) to scrape over the CPU & remove the excess.

The idea of the thermal paste is to fill in the minute air gaps between the CPU & the heatsink. It's not meant to go between the metal of the heatsink & the metal of the CPU, just fill in the (very) tiny gaps.
The heatsink compound transfers heat much better than air does, but not as well as metal to metal contact.

Yep, Kittyman had this one, spot-on, as one might expect. It may not be much of a 'marker', but on the Q6600, I have occasional use of, the temp spread is from +1 C to +4 C over ambient temperature at idle. Typically, where it operates, that means idling at 30 C - 33 C. However, as per my main, it does not use an Intel HSF....its the OCZ 'clone' of a Scythe Ninja (I use a Ninja 2 with my E8400 - the Ninja 3 is actually identical to a design I came up with about 5 years ago!). If you are using a stock Intel HSF, get rid of it! I'm sure that you'll find plenty of advice here, as to what is better - most are better than an Intel unit, to be honest!

Yes - as far as thermal paste is concerned, use a vanishingly small amount.

Interestingly, I read this several years ago:

http://www.dansdata.com/goop.htm

Even though it is old now, the principles involved still apply.

In fact, I use plain old Vaseline (petroleum jelly) for my thermal goop/grease.

It doesn't evaporate, it stays put, it doesn't clump up or dry out, it is easy to clean up AND it costs next to nothing.

I have used it on all my various crunchers for years with no ill effects, and I run mine 24/7/365.

I'm a "long grain rice" person with thermal paste, put only enough paste dead centre about the size of 1 grain of long grain rice then put the HS straight down on it.

Also, those extra hight Intel HSF's were only a few degrees better than the standard 1's, which means they are still not great so looking for something better before next summer would be a good idea.

I've had a Thermaltake Big Typhoon on my Q6600 @ 3GHz since I built it 7yrs ago and it runs 22-26C above ambient under full load on the hottest core (I can't tell you about idle as it rarely is and I've never worried about checking at those rare times).

Cheers.
