My cpu gets abnormally hot (85 C load after 5 hours ). however, I have a good cooler (the zalman CNPS7000B-Cu) and good case airflow. I have an intel 3 ghz, a gig of kingston ram, a D865GBF motherboard and an x-connect ultra. How much would removing current generic thermal paste and reapplying AS5 help? any other suggestions would be appreciated.
Removing the generic thermal compound and replacing with AS5 should help a ton, however... I would make sure you aren't creating a vaccum around your cpu (make sure the air coming off the hs has somewhere to go), and make sure your hsf is seated properly.
Id definitely make sure the heatsink is making proper contact with the processor-and that the heatsink's fan is working properly.
have you tried the finger test on your heatsink? heatsink cold to touch, temp reading high - bad contact heatsink hot to touch, temp reading high - inadequate cooling solution, try replacing thermal paste, if problem still persists, change the heatsink.
If the heatsink is hot to touch. Then changing the thermal interface material will do nothing, it is already doing its job. Also I dont believe that Arctic silver will make a great deal of difference over properly applied generic paste. My money is on the HSF not making good contact. Unless.... you have the fan speed on too low?
my heatsink is very hot to touch after several hours... the fan is spinning full speed... i seem to have had many heat problems, but im not sure why. i think i have adequate fans (3), and im running with my side off.
does your psu sit above your intake? if yes, and the psu is exhausting air, that might not be a good thing.
i have an x-connect above my intake. i havent determined whether that fan sucks or blows, so i dont know...
Usually PSU fans take air out. So that means you ahve 3 sucking air out, and 1 taking air in. That's creating a vacuum...you probably want to change two of your fans to blowing in.
I would be worried about a vacuum, it's more common than you think, and this sounds exactly like what's going on. Make sure you have an equal amount of air coming in as going out, and that there aren't tons of intake fans around your CPU.
are you using the "fanmate" supplied with the cooler?. if so, then taking this off and pluging the cpu fan directly into the motherboard will give it a few hundred more rpms which could more or less make a difference, but alot. Either way, its worth a try. I would also check the the motherboard is not throttling the fan, and possibly even connect the fan directly to the powersupply instead of the motherboard
85C? theres somethign bigger wrong than the oreantation of a few casefans mate 1st take the side off the case. Does the temp change segnificantly? If no then your case cooling is fine Whats your ambiant (room tempreture)? must be high if your getting those temps even with a presshot! Maybe the temp sensor is playing up slater..
Is the system stable, if so I'd say the temp sensor was probably wrong. A very common issue, which can on occasion be cured with a BIOS update (not always though)
