hi guys well as ya know i oc my i5 2500k to 4.5 stable at 1.235v i want to mess around to get 5ghz just wondering what kinda air/liquid cooler will be able to handle 5ghz below 65c at max cpu usage. i want 5ghz just for show ik i don't need 5ghz for gaming but i did buy a oc protecting thing so even if it blows up i will get a new 1 . this was my last result
thnx

5 GHz at those temps is a tall order, you'll need some serious cooling. My 2500k runs at around 74C at 5 GHz with a Hyper 212+ and a pair of Cougars on it. Single cougar cools just as well, but a pair can do the same job with less noise.

Really, the important thing to consider with temps is your voltage. Voltage has a much greater impact on temperature than clock speed. Keeping your temps low is all about finding the minimum voltage to get your OC.

That said, if you only want bragging rights on your OC, it's fine to run the 2500k in the 80s for a few minutes. If you ever break 85, though, immediately stop what you're doing and let the chip cool down. I've been running mine at 4.9 GHz because I can keep it under 70C and right at 1.4v to do it.

Takes more than 1.5v to get to my max OC of 5.25 (you can see the link in my sig), and Prime95 took it to 90C in no time flat. I can get to 5.35 if I turn off a pair of cores, running at a frosty 65C or so. Planning to try to hit 5.4 GHz as dual core this weekend for some single threaded benching, I think I can bump up my BCLK and hit it. It's been responding well to up to 104.5 BCLK so far.

i can spend about 150$ on a cooler lol ik what a waste but still its just for show. and nice o,o 74c i did 5ghz ones but in like 15min the temp where about 80c -85 with the evo 212 and if i recall the vcore i was using i think it was 1.4x-1.45 and yea most of the cooler i hear that are good for oc are the h100 h80 Noctua NH-D14 120mm & 140mm but i think those cooler wont be able to keep the temp at -65c

oyea it doesn't really have to be -65 at list -75 with prime95 and with gaming 65-

Skip the H100, it's overpriced junk. If you want to dump $150 into a cooler, pick up one of the XSPC Rasa kits. They're real water cooling, and a great entry level kit. Planning to pick one up myself this summer.

One of the Rasa kits would easily keep your CPU at 65c or lower, even with a really high Vcore.

I run my rig 24-7 with a 4.8ghz overclock 1.384 V i use XSPC Rasa RS750 240 my temps are 61C under full load

The NH-D14 will keep your temps at around 75C with a i5 2500k with a 5.0ghz 1.4v at least it did for me :lol:  that heat sink is a straight beast! :D  i don't recommend running your temps so high though

The triple wide radiator in the 360 won't fit most cases, so unless you know your case can handle the massive rad, go for the 240.

Great thing about the Rasa kits, as well as any real water cooling (over closed loop garbage) is that you can always upgrade the kit later. If your cooling fluid is getting too warm, you can get a better radiator. Not enough dissipation into the fluid? Better water block, though the Rasa kits have really good blocks in them.

The downside is the slightly higher cost over the H100, and the difficulty in setting up and maintaining a real loop.

The H100 is water cooling for dummies. Nice and easy, but you don't get the results of real water. Top of the line air coolers are just as good as the H100, on top of being quieter and cheaper. I really can't say just how big a waste of money the H100 is.

I totally agree with willard about the H-100

will there be any problems using it on a Raidmax Aeolu Case. link http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Hmmm.... that's a small case i am not sure maybe willard would be able to answer your question better i do measuring before i bought anything for sure

i got the case about 8month ago at cyberpower and yea it shows on cyberpowerpc that it cant handle
CyberPower Xtreme Hydro Liquid Cooling Kit 240MM
Asetek 570LX Liquid Cooling system w/ 240MM Radiator
CoolIT ECO II-240 Extreme Performance Liquid Cooling System 240MM
CyberPower Xtreme Hydro Liquid Cooling Kit 360MM
so im guessing it wont

I think a XSPC Rasa RS750 240 would fit it be a tight fit though

I'd recommend measuring the case to see if it will fit, I don't have any experience with that case. It's also possible to mount the radiator outside the case, but unless your case has water cooling grommets already, you'll need to drill them yourself, plus spend a bit more on the proper mounting hardware.

There is also a 120mm Rasa kit, but I don't think you'd get great results with such a small radiator. High OCs dump a lot of heat into your water, and if your radiator can't dissipate the heat, your water is just going to keep getting hotter and hotter, and your temps will creep up steadily.

Yeah, if you'd read farther down into that post you'd have seen:

I don't run it that hot, or with that much voltage (takes close to 1.5v to hit 5 GHz). Maxes out in Prime95 at around 67 at 4.9, regular use barely breaks 60.
