Hey guys im building my new computer as we speak , i need to know i have a thermalright extreme heatsink and a intel i7 920 processor is it the pea sized dot of thermal paste on top of cpu that i should do ?



or some other method ??

Best solution

Put a pea sized drop on top of CPU and put the HSF on it. My preferred method is to apply a very thin layer using your finger covered in cling wrap.

Small pea, bigger than a grain of rice.

Go to the arctic silver web site. They have a pictorial tutorial on how to apply AS-5 to the i7 cpu.

41c seems a bit hot unless your room is very hot. Perhaps you used too much material or did not mount it properly.


Push pin coolers can be tricky to install.
A bad installation can lead to higher temperatures, and even cpu throttling.
With the pc powered down, gently rock the cooler to see if it is on solid, or if it wobbles a bit.
Push pin coolers are best installed while the motherboard is outside of the case.
You need to be able to look at the back of the board to verify that
all 4 pins are completely through and locked.
Play with the pins on the cooler first, so you can see exactly how they work.
Read the instructions that came with your retail cpu.
When pushing down on the pins, do a diagonal pair first.
If you don't, it is hard to get the last pin in.
Don't forget to clean the parts and reapply fresh thermal compound every time.
Don't try to reuse the TIM.
Rubbing alcohol is OK as a cleaner.
I use a paper coffee filter to clean with because it is lint free.
Any name brand TIM should be OK(as-5, Mx-2, etc.)
When applying the TIM, don't use too much, because it can act as an insulator.
Don't apply too little, either, because it won't spread and fill the microscopic
imperfections in the surfaces. A dollop about the size of a grain
of rice should be about right.

Never trust the BIOs temps. Use one of these, I like HW monitor best.

Benching software and such is very varied. I use these for each purpose:
These are pretty standard and used by many.
Monitoring the PC temps overall: HWmonitor aka hardware monitor
CPUZ for CPU info
GPUZ for GPU info
CPU only: RealTemp
GPU only: ATI Tool, I have a Nivida GTX280, so it works on Nvidia

Loading/benching tools:
CPU loaders: Prime95 and OCCT
GPU Loaders: ATI Tool and the best one is Furmark, nothing pushes the GPU harder right now.
Benching for overall graphics/gaming performance is 3DMark06

ok un mounted it and looks like theres was too much thermal paste retrying with less

temps are now around 35c so im happy , let me know if those are more normal or if i should try again .

^Yup. Those look normal. More importantly, what are the load temps?

have not tested that installing os and updates right now. what should i use Shadow703793 for testing temps at full load ???

Darnit? I posted each and every program you need. You can use Google right?

Run prime95 until the increase in heat has stabilized at it's maximum. Select the option to check for rounding errors. You should get NO errors. I normally use speedfan. When running prime95, I use the graphic chart display to show the cpu temperature. It is easy to see when the temperatures level out and no more testing is useful.

ok speed fan with prime 95 after everything was installed was saying cpu was ideling at 45c and stable load temp of 68c , those seam really high but damn i dont know .

^Give us the RealTemp readings. You need to calibrate SpeedFan to get accurate temps.

im not sure how to configure speedfan . but i think i know what ya mean know . are the temp reading im getting false because the core 1-4 readings are much lower like 29-30c . Let me know what ya mean . thanks Shadow703793

Video is to help compare with what a finished pasteing would look like. As well as one way to do it.

Testing, by mainly CompuTronix (seed the C2d/i7 temp guide sticky) that with out calibration SpeedFan can be off by up to 5-12C.

Depends on the cooler. If it has heatpipes exposed, I spread it all over the processor. Otherwise I use the Arctic Silver method.
I had a problem with the Arctic Silver method when using it with a cooler with heat pipes exposed. It did not spread evenly.
