I have an i7 920 overclocked to 4.4ghz and i want to buy the corsair h70 water cooler.I want to ask if it's the proper water cooler for my overclocked i7 cpu (at 4.4ghz will be very hot).
 
Yeah, I have a 920 (D stepping) at 3.8G with 1.22V and a true copper heat sink and it will hit 70C at times under full load. If I bump it up more then 3.8 it starts to require insane amounts of voltage and the heat output goes through the roof. I also have 2 X 120mm Noiseblocker M12-S3-HS pulling air in a 2 blowing air out as well as the PS fan in a full tower case. I have 2 of the same fans on the heat sink in push/pull.

I am curious what your temps are currently.

why use a swimming pool pump when u can just use a swimming pool to dump your heat? just go buy those 2000gal inflatable pools and BAM! res, rad, and fans all in one. ill be impressed if u can somehow manage to install that in a room instead of outside your house.

"Hello pool company, do you have a tanker to fill swimming pools......... great......can you make that Distilled Water please....." :lol:


Sorry mariosarmy, we are just having a little fun. To run an i7 at 4.4 GHz (24/7) you would need to go custom water (approx. $350) to keep the temps in check.

I haven't even seen any decent reviews on the H70 yet to see how capable it is, they should start hitting this week, but even if it is an improvement over the H50 it still wouldn't be enough for 4.4 Ghz with decent temps.
 
I agree that you will need water cooling if you are going to do 4.4G 24/7 and want a 100% load stability.

Mine at 3.8 with 1.22V and the True Copper heat sink can hit 70C under full load with both GTX 480's fully loaded too.

If you don't want to waste $300+ and hundreds of hours on a custom water cooling system, you can try out some of CoolIT's stuff.

I've heard great things about this, especially in push & pull. I'm running the 120mm radiator version in push & pull right now, and its keeping my i7 860 @ 3.8 ghz at 35 idle and 69 max under Intelburn.
 


I'm quite fond of the H50, having used them on several I7's with great success, but to say that water cooling is a waste of both money and the amount of time that you claim is just silly

Sorry, bad choice of words.

Basically what I was saying was that if you don't want to put the time and money into a good liquid cooling system, then some of the closed circuit systems can yield very nice results.
 

I agree that they can yield nice temps but with an overclock as high as the OP is doing the cooler the better, and at 4.3 things start to warm up even with an H50 modded with a dual rad.

No. Most likely won't cool well enough. Get a Danger Den or Swiftech system if you have to go with a full kit.

I don't think you understand the amount of heat involved with running your chip at 175% its stock clock. You're going to need a lot of cooling, and all this cooling will end up being in the high $200s and $300 range.

What speed and temp are you really at? I don't think you can run a 920 long enough at 4.4GHz with an air cooler to be sure that it works without killing it. You might set it to 4.4 and run it long enough to get a splash screen, but the temps go up very fast.

Not running at 4.4 GHz.

Do a little research and pick out the best components you can afford. That's the only way you are going to reach your goal.

again...what are you using this 4.4ghz for? if its for show then just clock it to that and get a screen shot and you're done. if it is for anything else please specify

CoolIT ECO-240 Systems ECO ALC 240MM is good because i have seen many water coolers and now i don't know which one is the best for my cpu.Also i have in mind the cooler master aquagate(it's expensive).I have contact with the seller that i have bought the cpu and he told me that he used thermaltake frio to overclock it to 4.4ghz.PLEASE HELP ME WHICH ONE TO CHOOSE.
