i7 920 Temps

post #1 of 16
Thread Starter 
Alright, I'm aware that this is probably the 100th topic opened about this, but each issue is different.

I'm running an i7 920 at stock clocks, a Xigmatek Dark Knight heatsink, Arctic Cooling MX-2 Thermal Paste, and I'm seeing around 70C during a full stress testing on LinX.

I'm aware that 70C isn't blisteringly high, but it still seems high with the stuff I'm using. The thermal paste is applied properly, and I've even tried different kinds of thermal paste (such as Arctic Silver 5).

I have good airflow and powerful fans, my room temp is 24C. I really cant understand where these high temps are coming from, I just bought the MX-2 after OCing my i7 to 3.8 and seeing over 90C in the hopes it would bring my temps down a bit.

Any ideas/thoughts are greatly appreciated.

Whats your voltage? What program are you using to monitor core temps? (use real temp or core temp), cause that doesn't sound normal. Mine hits 60-65 linx at 3.6 ghz and if I remember right your cooler is similar in performance to a 212+. Though note these are the same temps I got at stock cloks and stock voltage (which was something like 1.23v) now I'm down to 1.15v, can probably go lower but gave up on the restarts. So try to find your lowest stable voltage for starters.

Stock, so whatever the default bios sets it to.

yeah 70c is definately too high for stock speeds, i reach 71 tops at 4ghz with 1.225v.

might be an obvious question, but are you sure you used the right amount of thermal paste?

*edit* maybe try set the voltage manually in your bios, if its set on auto it may be raising it too much for some reason or another

Positive, I've done it a countless number a times, and each time I take it off I can see a perfect size circle, not overflowing and not touching the ends.

Set your voltage manually, the auto voltage is usually too high.

And your ambient temps are pretty high (24C), so this will have quite an effect.

Still though... At default I shouldn't be hitting 70. Something isn't right.

High enough to cause this whole thing?

Ambient temperature is not the cause. Have you tried another CPU cooler?

I had an issue with my previous cooler (the stock one) I was getting 100C while not even overclocked when folding. (surprising I know, but I swear it's true). So I got this one. But to answer your question, yes and no, I have use another cooler, but not another aftermarket cooler.

The fan blows at 74% when at max load, so when it's at 70C the cooler is blowing at 74%.

I will note that I also had to RMA my motherboard shortly after I released that I was running at 100C, they could have been related but I doubt it. Meaning that my current motherboard is new.

You won't get anywhere without actually looking at your voltages, what is CPU-Z showing as your CPU voltage when it's under load?

And you're not going to get great performance on the Xigmatek Dark Knight, it's towards the budget end of air coolers.

But mainly we need to ascertain what your voltages are, because temps without voltages mean nothing in terms of how well/badly your cooler is performing. Just saying 'stock voltage' doesn't help.

Also, take a pic of the inside of your PC, showing the layout of your cooler and fans etc. Often with cooling problems like this there's just some issue you might have missed that we might spot for you
