Should I reseat my CPU cooler

[Lefti]

Zalman CPNS9700LED on a Q9550 with Noctua NT-H1 Thermal Compound.

The temperature difference of 5 degrees always seems to be there, is this normal? I would be happier if all the core temperatures were similar.

Perhaps one half of the CPU does not have good contact with the heatsink?

I would suggest your assumption could be correct. Been undergoing some heat problems myself recently and have done a chunk of reading on thermal paste application of late. From what I can ascertain quad cores my be better off having a thin line of thermal paste applied rather than the traditional rice grain sized blob in the centre.

I wonder if a tiny blob over each core might be better though I am purely speculating.

Yup sounds like you need to re-apply that thermal compound. Personally I always prefer to use Antec Thermal Silver ever since my K6-2 . Anyway you'd best re-apply it with a thin line of even paste since Noctua NT-H1 is some good stuff and you shouldn't have that big temperature difference if it was on there evenly. I make sure to put a thin layer across the bottom of the heat sink to ensure better heat transfer.

make sure the thermal paste is very thin and push down the cooler to make sure the paste spread evenly.

Thanks for the replies, I'll remove the heatsink and re-apply the thermal paste, i went with the blob in the middle approach last time.

I've done a bit of reading on the subject and saw some people put a blob on the cpu and then spread it using a credit card or similar to get a thin layer across the whole surface of the cpu. What opinions do people have on this method?

 

[iluvgillgill]

or you can use some cling film to wrap it roung your finger and spread the thermal paste

 

[dimothy]

wow, the cling film method sounds good. alot easier than trying to manhandle a credit card round the retention bracket and probably much cleaner! Good tip.

 

[iluvgillgill]

just remember dont wrap food with that cling film afterward!lol

mmmm i still disagree with the cling wrap/condom idea 🙁 just grab a xiggy and chuck three lines on each of the heatpipes

 

[iluvgillgill]

^i never said this method dont work><😛

tru...tru... hey gill u hear about what happened to lupi? 😛
