Hello. First time overlocker and aftermarket cooling here.

I have a few questions, but first I'm going to lay out all my hardware specs.

Case :

Running Windows 7 pro 64 bit.

Processor : i5-2400 CPU @ 3.1GHz

Graphics Card :GeForce 8800 GTX 550Ti



850w Power Supply

MSI Z68A-G45 (B3) Mobo


Now onto my concerns and questions.

My first concern is overheating. I've never done any aftermarket cooling. I have recently been using more and more cpu usage, and im up to about 40%-45% cpu usage at all times. Using CPUID Hardware Monitor my cores are running at an average temp of 75 degrees celcius (around 170 degrees F). Looking around has told me this is too hot for an average temp so I am considering liquid cooling.

#1 : Is this product what I need to be looking at? Will it fit inside my case comfortably? If not, what should I be looking at?

#2 : If I overclock my i5-2400 will it still keep it cold enough even with a say... 70% load?

#3 : If I upgrade to a decent i7, will it still be enough cooling if I put it under 50-60% load?

I understand I'm asking alot, so even if you can point me in the right direction I will be very greatful. :)

The first issue I see here is that you have a "locked" processor, that is the CPU multiplier cannot be raised (it can be lower though). With the Z68 chipset on your motherboard (which would be awesome if you had a "k" unlocked processor), you are severely limited on playing with your FSB, in fact few Sandy Bridge overclocking guides even go into manipulating the FSB.
An upgrade to any "k" model processor (IB with BIOS update) will enable you to overclock.
The H80 should fit your case (most any case) without issue.

Ouch, I did not know this when I bought it. Noob mistake =X

How can I avoid this in the future? What am I looking for specifically?

If I upgrade to an overclockable i7, should the H80 provide enough cooling with a big gaming load?

If you're mostly looking to use your rig for gaming, I'd suggest an i5 2500k processor which compliments the abilities of your motherboard/chipset nicely. The Sandy Bridge will also provide for higher clocks than an Ivy Bridge CPU (which tend to run hotter). If you are doing other tasks that require (or perform better with) hyper-threading, then the i7 "k" model would be a good choice, otherwise it's potential (and extra cost) is wasted.
The H80 is a very good cooler but, if your case supports it and you're interested in an all-in-one, I'd suggest the H100 which performs better than most air coolers on the market today

Dont need a Bios upgrade for Z68 boards to have Ivy Processors in them, that's H61 and P67.

If its just a gaming rig, then an i7 is pointless. Sidegrading to a 3570k isnt worth it IMO just for the overclocking ability. Would just sit with what you have until Haswell, when you can properly set up an overclock capable rig.

None of the all-in-one watercoolers are worth it except the H100 IMO and even that's debatable as its equivalent to a Noctua NH-D14 in performance, which is cheaper (though I personally would get the H100 over the Noctua, thing is huge and ugly as).

+1 to manofchalk

however as is the h80 is more then enough for your cpu, due to the lack of overlocking, you mostlikly see 63-64 temps max on 100% load.
Another cpu cooler you can try is a cm 212 or a ets t40 both are around 40 dollars US.
