My CPU temps have slowly gone up over time :confused:

When I first built the system, my idle was in the high 30s and load low 50s, now my idle is low-mid 40s and load upper 50s eventually hitting 60C

(this is stress testing)

Has anyone noticed familiar? Should I re-do my heatsink? Could airpockets have formed in the thermal paste?
 
Happens all the time.

AS5 "cures" and dries out... Lots of vibrations to the case, or just the stress of heat/cooling cycles over time, will wear out the bond.
 
its probably just dust, try cleaning out ur system.

Edit: Also try doing some cable Management and move any cables that are in the way
 
Another vote for dust- you mention "re-doing" your heatsink. Are you running something other than stock?
 
Yeah its not a stock heatsink - scythe mine.

I'll check for dust... but wouldn't my GPU also have a temperature increase? (which it hasn't)

I don't think airflow is an issue, I have 2x intake fans, one is rated 90CFM the other 60CFM, they are both filtered, and one non-filtered 90CFM fan.
 
What's the time delta we're talking about here? That is, how long ago was it that you built the system? Arctic Cooling recommends that Arctic Silver 5 be reapplied about every 6-8 months.

When I decided to lap/reseat my HSF and put an aftermarket HS on my northbridge, I got me some MX-1 compound. This stuff actually gets more effective as it cures, it's completely nonconductive, and it's good for years without a reapplication! And it only costs like $1 more per tube. Why MX-1 isn't way more popular than AS5 is beyond me. (But I'm willing to admit the possibility that y'all know something I don't. Enlighten me?)
 
The chart in the middle of this article concerning a 5 week test of Artic Sliver performance over time might explain some of it.

Interesting about the comment above about reapplying AS peroidically, AS is redoing their web site so the FAQ is gone, but nothing is mentioned about reapplication of AS5 in the instructions and I do not recall it being mentioned before by the AS people. What I mean to say is that it couldnt hurt, but I dont recall the AS people ever saying it was recommended/needed as it would have been a red flag for my use of their product, I dont tear down my systems even yearly once they are up and running properly and I would have noticed. The Dow Corning thermal grease used on our telecom power supply switching transistors was expected to last 30 years and did.

Anyone else recall a reapplication recommendation from AS ?
 
I carry my PC to LANs a lot, and I have to remount the heatsink and reapply thermal grease all the time. That's always solved the problem for me.
 
yes, reapply arctic silver.

and actually, i recommend arctic silver ceramique. its just as good as AS5 (withink 1 degree or so) but is a longer term solution. sort of a set it and forget it. I change my ceramique like once a year.

also, a can of compressed air can do wonders for your entire computer. don't just target the heatsinks and fans, spray the whole thing.

What case are you using? Could be an airflow issue.

I recently dropped 19*C at load just by replacing my case.

19 degrees C is pretty extreme; I'd be inclined to think temperatures dropped because you got a new heatsink and applied some AS5? When you transfered everything over to the new case did you re-mount the heatsink? Maybe the heatsink wasn't seated properly until you moved it?

I got myself a new silent case with super low air-flow and a new silent Zalman CPU cooler. Processor temps went up about 8 degrees C across the board but interestly enough my max overclock went up about 150 MHz.

Absolute temperature reading isn't everything; making good contact with the CPU mating surface is very important, primarily because the internal temperature reading doesn't identify hot spots. Lapping the heatsink and CPU heat spread to a mirror finish can really go a long way. I remember when overclocking the flip-chip Pentium III's, I had one of those massive slot-1 heatsink and overclocked my Pentium III 550 to 953mhz. Then I got a 700 and using the same heatsink went to 1012mhz. Sticking my PC out in the sub-freezing temperature one night (as an experiment) didn't buy me even 1 extra mhz of FSB; I cranked the voltage way up and the CPU was still 4 degrees C according to motherboard monitor. I knew the memory and motherboard could handle higher speeds because the PIII 550 already ran at 173mhz, the PIII-700 was only running at 144mhz. It was lapping the heatsink to a mirror finish was what allowed me to push that PIII-700 beyond 1ghz, no doubt about it.
