Need some help with c2d e8400 cooling

post #1 of 11
Thread Starter 
Hello, I recently installed Arctic cooler freezer 7 pro onto my c2d e8400, and the results have been underwhelming. Im getting 45C idle/56C load on stock settings, which seems too high, especially since stock HSF outperformed AC7 on idle by 5C (not on load tho). I cleaned cpu properly, applied arctic silver 5, and reseated the HSF numerous times (each time cleaning and reapplying paste) with no change in performance.

Anyone have any advice how to reduce my temps?

Your temps are fine. Load temps are what matters, and your AF7 performed better than stock on load.

Those temps are fine.

they fine for stock but i want to OC in which case theyll go even higher. on 3.6ghz my cpu is at 45 idle and maxes out at 59C load

You're pretty adamant about lowering your temps. You can do 2 things.

Lower your ambient temps or get a better CPU cooler.

but i just bought a cpu cooler and now im broke

how do i lower ambient temps? i got 1 80mm front fan pulling air into case, 1 120mm fan pulling air out of case, one fan cooling cpu from side, and one fan cooling the top of the cpu..

Open your windows/turn on the ac (even though it's february )

59*C load isn't bad. I run at 73*C load temps and I'm far from dangerous temperatures. You really shouldn't worry about temperatures unless you've turned off Thermal Control in the BIOS.

If you want to be safe, avoid 100*C+
If you want to avoid problems and shutdowns, avoid 80*C+

But below that shouldn't be an issue. The temperature listed on the Intel site is for tJunction, which is about 10-15*C lower than your core temps. So you can reach about 85*C+ before being higher than their recommended max.

i thoguht the max thermal spec for 45nm dual cores was 71.2C. at least thats what it says on intels site.
post #10 of 11
They also say not to go above 1.36v

Anyways the AC7 isn't exactly a juggernaut of a cooler. Here are some things to consider.

1.) Are you running IBT or Prime 95/orthos small FFTs? If running Intel Burn Test, don't worry about your temps. It's extreme for the sake of being extreme, stress-test wise.

2.) Do you have a bolt-thru kit for your HSF? Because the push pins are horrifically bad at keeping temps down.

3.) You can also figure out a way to arrange your case fans so that air efficiently blows through the case. This involves cable management, checking for your fan CFMs and arranging so that you have either neutral pressure or slightly negative pressure (which is what I prefer).

I use orthos small FFTs to check stability.
