Currently using i5-3570k 3.8Ghz
my old cpu cooler thermalright silver arrow sb-e at idle is only 30-35degree and after i change my cpu cooler to h60, reapplied my thermal paste(rice grain size) and the idle temp is higher than ever. it's around 60 degree idle and tested playing game at full load, it goes up to 100 degree. i tried reseating it 3 times and still the temperature is the same. the 4th time i reseat it. the temp drop to 46-50 degree. is my cpu cooler defective or is the thermal paste not enough?

Then yes. Get it replaced as soon as you can. In the mean time, use your old cooler if you still want to play till your replacement H60 comes in the mail.

If you used the same thermal paste in both cases, then it would either be a malfunction in your cooler or you had some air pockets in the thermal paste (you just didn't apply it right). But by the looks of it, for the fourth time reapplying it your temperatures are normal so it must have been the way you were applying it.

just an update, it went worse. after playing 1 game the temp goes up to 90 degree... so is it because of the cpu cooler?
