Hi, after I switched to a new motherboard the Asus p8z77-v and overclocking my CPU began running very hot. My cpu used to run at around 25c but it wasn't overclocked. After putting everything back together replaced the thermal paste with arctic silver 5. It has been overclocked to 4.4 with the asus turbo utility. Now it runs around 50-55c idle and when running prime the temperatures jumped to 95c where I immediately shut prime down. My cpu used to run at around 25c but it wasn't overclocked. I have the Asetek 510LC Liquid Cooling System (Push - Pull setup which is blowing from outside into the case). The pump seems to be running at 1400rpm ... could this be the problem? I'm also thinking I may have put too much thermal paste. Thank you for your time.

Make sure you spread it good, that can cause a issue. If it is the cooling,then you might need a new one: http://www.pccasegear.com/index.php?main_page=product_info&cPath=207_23_845&products_id=18670

Some people have had issues with this cooler in some threads, check this out:

Thank you for the reply. For the thermal paste, I used the pea method. So I'm hoping it spread out with the pressure of the watercooler's heat sink. As for the watercooler, I'm not really sure if it's giving cold water back to the cpu because when I touched it, the entire radiator and water reservoirs were very hot.

Well the temperatures are NOT ok because like I said earlier, with prime it jumped to 95c and I'm sure it would keep climbing.

Check to see if any air bubbles are in there, if air is in there then the heat cant transfer properly.

How do I check? Reapply it?

Going to disagree with you there, IMO the manually spreading method is much more unreliable.

Coverage isnt the key with thermal paste, its that it can fill the gaps between the heatspreader and the heatsink.
 


Each to their own I guess. :)

Call me a traditionalist, but I like to make sure that I've covered the processor evenly.

Hmm, dont know about traditionalist, Ive been applying it and spreading it with the heatsink since we had upgraded cpu coolers.

Coverage really isnt important, the job of the paste is just to fill the gaps, its still not as good at conducting as metal on metal.

If you suspect you put too much paste on then this is likely the issue. Take the sink off and clean the spread away, perhaps check up with some guides online to see how think they manage to get it.

It can be difficult to do the manual spreading way, which is why it is best to avoid it, however it will get you the best coverage. When you put a pea sized piece and let the sink spread it, unless you're guaranteeing that you're holding the sink flat, and an even amount of spread goes each way, then it will never fully cover the area. Manual spreading can ensure you cover the whole chip and give some great results, however you must be careful not to spread it uneven in the slightest, since the sink will sit on the highest point and may not attain full contact. Also, you must ensure it is not too thick, because you'll then either see poor heat removal or overflowing paste onto the pins.
