As many of you know I've had a major leak with a Raijintek Triton and now I'm having to use a Hyper 212 EVO, with a double fan setting one either side. However when using Prime 95 the temps are shooting up to 96C within 1 second of launching it
Any advice?
Editing using realtemp with prime version 26.6 they are only getting to 74C
Sounds like you dont have great contact with the CPU if your getting real high temp so fast. I would take it back off, clean the CPU and heatsink surface with IPA and make sure theres no dried on lumps that could be causing bad contact, then stick it back on with some new paste.
What temp do you get in RealBench? I havent used prime 95 in ages as it gets the Haswell chips a bit too hot.

If your averaging 65 then it sounds fine to me, my cpu nearly hits 60 on a custom loop in real bench and im only using a little more voltage than yourself so i think your doing fine on a air cooler. I would just stay clear of Prime95 as it sounds like thats the problem.
Sounds like your overclock is too much for the little 212 to handle under full load. Simple solution is don't run Prime.
212 is definitely not one of the high heat removing heat sinks.
If you want more cooling get something like the Alpenfohn Olymp, R1 Universal or Ultimate, NH-D15S, NH-U14S, PH-TC14PE, etc. They easily have 10+ C more cooling tha 212
i agree with doyll, don't use prime for now, in no situation will your computer be stressed to the point of matching prime, so there is just no need for it.
i vote for the PH-TC14PE, i have never seen higher than 60 with a 6700 at 4.6, although i have two noctua 2000 industrials on mine running from a grid v2.

So if where you stated in first paragraph you were using v27.1 onwards you would hit those temps when the combo is i7 4790K+OC+212 Evo. The lower temps on v26.1 are due to no AVX code being run.
I would not run Prime95 with AVX on that CPU+OC+212 Evo.
I stopped using Prime95 on Haswell/Devil's canyon TBH .
On my current and past DC chip I used:-
i) x264 first to gauge temps for OC.
ii) next RealBench stress mode as that gives CPU/GPU work out.
iii) finally F@H on CPU/GPU.
OC in sig: x264 48 loops/~8hrs stable, RB Stress mode 4hrs stable, then did some gaming (~2hrs) and set the rig to run F@H, 17hrs stable. As you can see from the clock the rig had been up for 31hrs . Seeing cooler temps than those screenies now as not have a Vapor-X dumping hot air in case .
Nice chip you have there, have ya thought about getting water cooler so you can get a bit more out of it? ya might get 5.1ghz on 24/7 voltage with a bit of the wet stuff.
Cheers , considered it but I'll be honest I'm a bit of a tight git, so WC out of budget.
Cooler was something like £15 2nd hand ebay. Mobo (new) had an Asus Front base panel FOC with it, which as I did not want sold on, netting mobo down to £100. At the time 16GB DDR3 on promo was £95, usual was £130 (how much it's slid in price now!).
It was my 2nd i5 TBH. First one touched 4.4GHz with 1.18V stable 24/7, but needed 1.26V for 4.6GHz. This one I bought on nice promo, using a cashback site was ~£130, once I sold the 1st one price averaged ~£140.
When I had the 1st i5 I thought the Ranger was holding it back with 4 phases doubled to 8, I had to keep myself from buying a Hero with true 8 phases.
You'll see a lot of settings are "Auto", this chip just OCs like anything , gave me a real buzz like the Q6600 G0 I still have.
This is all I change from bios defaults.

Wow just done a quick test of Prime 95 just to compare and it's only going up to 68C and with realbench 64/69C and that's with a Noctua NH-D15S X2 fans... Incredible
