Just put a new liquid cooler installed the other day, pretty new to liquid cooling so I got the XSPC raystorm d5 ax240 kit. After doing some overclocking I managed to get to 4.8 Ghz stable at 1.3v and my idle temps fluctuate between 33c and 43c. While under load it never gets above 64c except during prime 95 testing. it gets to about 73. I was wondering if all of this sounds safe, or if maybe I should tone it down on the overclock? Thank you in advance!
 
If you got 4.8 and it's stable under prime95 v26.6 small fft's, intel burn test etc while only maxing at 73 under stress - aka, no bsod's or anything, I'd say you got a great cpu. Especially if doing all that at 1.3v. The idle temps are a little warm compared to many I've seen but it depends on the room temp and inside case temps as well. The max temp sounds safe, under 75c and the voltage is within safe ranges. Mine wasn't happy going that high on air, but not sure if a better cooler would help I think my chip's max is around 4.7 so I backed it off to 4.6 to keep similar temps under load (more in the mid to upper 20's at idle) at around 1.285v . Generally 'safe' is considered under 1.4v vcore and closer to 1.3v is even better.

If you do experience any random crashes I'd just ease it back to 4.7 if it were me. Otherwise I don't see any real concern keeping where it's at. Usually when they hit 4.8 the vcore or temps are higher which is more cause for concern.

Thanks guys, it just kind of worried me because when idle, the temperatures fluctuated kind of a lot for me to be comfortable, but when I'm playing games they seemed pretty stable. It just freaked me out a bit lol.

I'm at 4.3 with a silent air cooler (temps are restricting me, 35' at idle). I also get these crazy temperature fluctuations, so don't worry.
