I just built my first computer and I have an i7 930. I was looking to overclock it from 2.8 ghz to 3.2 ghz. Before I made any changes, I downloaded Core Temp and Prime95 to test the current temperatures and this is where I ran into problems. My idle temperatures are around 45 C and my load temperatures in under 3 minutes of Prime95 were in the 80s. I would like to keep it below 75 C.
I am using the stock heatsink and fan that came with the i7. I figured maybe my temperatures were due to me messing up the already applied thermal compound on the heatsink. When I first installed it, I had to remove it again because I had the power cord for the fan in the wrong place.
Hoping this was the solution, I removed the old thermal compound and I applied this thermal compound: Xigmatek PTI G3606 http://www.newegg.com/Product/Product.aspx?Item=N82E168.... This was the first time I applied thermal paste and I found various methods to applying it online, I ended up using the included spreader stick with the PTI and applied a thin layer across the CPU.
After booting up and running core temp, my idle temperatures are still around 45 C and I got the same result with Prime95, 80 C in just a few minutes.
Is this the best I can expect from the stock heatsink and fan? Am I applying the thermal compound incorrectly? Do you have any other solutions or ideas for my problem?
