CPU hot after system build

Well I had a couple of attempts. Once, I put a small line of compound, and spread it around completely. But that was too much, I had bios temps of 55c.
Then I tried again with just a small pea size in the middle of the cpu, placed the heatsink on and swivelled it abit to help spread it around. then screwed it down.

Maybe it wasnt enough this time.

And yes I did clean off the heatsink and cpu each time. firstly with tissue to remove the old compound, then with some compound cleaner using cotton bud sticks.
 
arctic silver takes something like 72 hours to cure or some such rubbish. MX2/3/4 takes like 5 mins to cure, but still, 81 is high for load. get yourself a TRUE or a TITAN :D

45 is fine for idle, my cores idle at around 40-45, although my load temps are like 45-50 :P
 
Perhaps it needs lapping. Unfortunately you do get the odd cpu that ships not entirely flat. Those temps do seem somewhat high for a cpu at stock speeds, especially on on aftermarket cooler.

Like you said. If it's screwed on tight and there's thermal grease on it. It's the only explanation I can think of.
 
ok. Im going to put the stock cooler back on because that should definitely keep it under control for stock use. And if that doesnt, then I must have some other serious issue.

And in the mean time, order a new cooler. Is it the Titan Fenrir youre referring to?

The arctic 7 does not seem to cover the heatplate on the CPU, at least on my AMD hexcore. I use the small grain of rice, spread with a credit card very thinly across the whole heatspreader before screwing down the HSF. I now use a TRUE which reduced my temps considerably from the AC7 (actually AC64 cooler). I get 41C at 3.5GHz under prime.

Well Ive ordered it now. Along with some mx-4.

Incidentally, which direction should the fan face on the heatsink, facing the exhaust fan (which is only a few centimetres away), or on the otherside towards the memory?

The heatsink is a pull fan right?

Edit:
I have a horrible feeling that my whole problem has been the heatsink around the wrong way. Currently the fan is next to the chassis exhaust because I was assuming the heatsink fan was pulling hot air out.
If its actually pushing, then it wouldve been losing a fight against the large exhaust fan.

on the arctic cooler 7 pro the air is blown

on the Fenrir you can decide which way you want based on the orientation of the fan, look on the side, on one of the sides will be two arrows showing which way the fan circulates ;)
 
Oh the shame! :(

Well, i turned the heatsink around and surprise, got 35c in the bios.
Idle windows was 40c.
A quick 5 minute run of prime95 got the cores slowly up to 75c.
But the second I stopped prime95, they instantly dropped to 50c, and then slowly decreased. (I guess prime95 is extreme testing isnt it?)

So its a improvement, not great but definitely better.

And I have the Titan on route now anyway.
 
ouch, thats pretty warm, and yeah prime is pretty stressing for a cpu

The titan should do a much better job, i fitted mine yesterday and it's amazing.
just make sure the airs flowing in the right general directions lol
 
Well 75c on Prime max load is good :D

But I agree, the Titan will definetly do a better job. Just make sure you place the fan and heatsink the right way round ;)

how long is that on prime for and what else is in your system, is it overclocked?

Just seams really cold, unless its the bios cpu temp and not the core temps?
Click to expand...

Rig is in sig, I have a fractal R2 full fractal 120mm fans

Its cold but i have decent airflow, and using the icdiamond compound i won brought temps down further buy 3.C ish

Prime is run for 6 hours at that temp ambient room at around 19. C

It really is a great cooler.

I have a C3 so 4.0Ghz here i come :P

will post a validate and speedfan once done .
