^^^ like dangtx said, you probably won't kill anything, as long as you don't go near 70C, and don't overkill on the voltage loads. u'll be fine, just be careful on those voltages.

i just use regular rubbing alcohol to wipe the paste off...make sure it's nice and clean, that's all...i usually squeeze out a line of paste, and then use an expired creditcard to spread it across, the lazy way to do it, i'm sure there are more professional ways to do it from articles on the web...

If you go with silent fans as i have they will actually be quieter then the stock case fans and really improve on your air flow

Currently it is running in stock speed (3.0 Ghz) with a coolermaster Hyper 212+ cooler using the thermal paste that coolermaster provided.

idle temp (recorded using AMD overdrive) is around 46 C, normal load (i.e. gaming) is around 48-50 C. Full load using prime95 large FTT after 6 minutes is 56 C and seems to be stable. (been 56 C for the majority of the 6 minutes).

It is in a coolermaster 690 II advanced case with stock fans. 140 mm front, 140 mm top and 120 mm back. The case is under my desk, which has poor ventilation.

Current outside temperature is 26 C. My room is very warm so I estimate it is at least 30-32 C in the room.

I heard from other CM hyper212+ owners that my temp is very high. they told me to reset it with reapply the thermal paste as I apparently didn't apply enough the first time. I did that and the temp is the same.



Questions.
Should I try a thermal paste like arctic silver 5 to reduce my temp?

How is my current temp?

Ok to OC or should I get a better CPU cooler?

Thanks!
Check device manager to ensure that you aren't running the AMD processor driver. The fact that your temps don't change much between idle and load sounds exactly like the issue I had when I upgraded from a 720be to a 955be and removing those drivers from device manager solved the problem.

If that doesn't do the trick... I'd have a look at your install. The idle temp is way to high even for a heavily OC'd processor. I had the hyper 212+ running on a 3.8G 955be and it idled under 35c. With the temps you're showing, and the fact that you're currently running at stock, replacing the heatsink isn't going to solve your problem.

There may not be enough force with holding mechanism. Try to twist it gently and see if it moves.

Good point... there's actually a thumbscrew on the top of the block that should be tightened down.....

IDK if his ambient temps are 30-32c it might just be the case's airflow and placement that is causing the high idle temps.

IDT that pressure is the issue since his load temps are still acceptable not great mind you, My 720 unlocked will hit 56c pulling 1.49v on a hot day.

It does move when I apply some force on it. There is a spider thingie that tightens the heatsink onto the cpu.. there is a screw in the middle of it. I didn't screw that screw as I thought it was there for the spider thingie to move around.. should I tighten it? It doesn't look it can be screwed.

This is the thumbscrew that needs to be tightened down.

Ah, I have bad news.. I tried everything here.. and I still have a core temp of 42-44 C while idle..

Here.. I posted my step by step of reseating the heatsink.

1. I opened my case..messy eh?



2. I took the heatsink off..



3. I wiped the CPU and the heatsink with 99% ethanol to remove old thermal paste.. then I reapplied some thermal paste to the heatsink..

4. Next, I took a plastic card and evened it out the best I could.. took me 2-3 minutes..



5. Then I tightened the thumbscrew on the spider thingie as suggested here.. and I even tidied out the cables..



Still the same temp!! I notice that the coolmaster thermal paste I have is kind of dry.. is not sticky.. I ordered some arctic silver stuff and they are arriving next week.. Do you think this could be the culprit?

I am out of ideas...
