Ok I am really annoyed now, spent the past week trying to get temps down and nothing seems to be helping.
CPU - i7-2600k
Motherboard - Asus Z68 pro
Ram - Gskill Sniper 1866 8gb
HSF - Hyper 212 evo with push/pull using the same fans from factory, believe they max at 82cfm
HDD - Spinpoint 1tb HDD Hd103sj x2
SSD - Crucial M4 128gb
PSU - XFX PRO750W XXX
GPU - Gigabyte 6850
Case - Cooler Master Storm Scout with an upgraded top exhaust fan from xigmatech and added a front fan in the drive bay rated at 60cfm
I have had a 2600k/p67/ hyper 212+ build in the same room, same case and had idle temps around 30-33 with load temps with prime 95 at 70 max.
Now this time, I have a hyper 212 evo with push/pull, and i am getting 36-40 idle and touch 65 at stock speed and touch 70 in 5 mins at OC at 4.3,firstname.lastname@example.org and go over 80 in 15 mins at which point i turn it off.
I have heatsinked it more times i can count now, barely got any difference.
Tried cooler master paste, AS5 and antec formula 6. not much difference in temps.
Tried opening the side window and blowing a fan against it and got maybe a drop of 1-2 degrees.
Please help, this is getting really annoying now.
Also does changing phase control, load line calibration affect the temps much? I set mine to Extreme/Ultra high to see if it did but didn't notice any difference.
That's odd, your temps were still extremely high considering your VCore is only 1.25
(To put it in perspective, even with my Hyper 212 Evo I was running around the high 60's at 1.310 Vcore for 4.5Ghz)
Still I think it's a pretty shoddy cooler and the Hyper 212+ is better (even though it's cheaper.)
But for 100, I really like the DH-14... But I've heard good things about the Corsair H100, unfortunately I've yet to use one so I can't vouch for it. Still for air, the Noctua is your best bet (But it's a MONSTER, make sure your memory will fit with it.)
Really would try and isolate the problem first though if I were you, those temps for that Vcore are just really bad.
With regards to water-cooling, I myself have been looking extensively into a higher end setup... But they seem to start at a minimum of 150, and just go up from there. (Especially when you begin wanting to cool your GPU's and mobo with it.)
But your best bet would be to ask another question in the water-cooling section of the forums. At least there people could potentially direct you straight to a solution fitting your budget.
