Hello everybody, I am building a new i7 system and i want a overclock of at least 4.0ghz... i've never overclocked before, but from what ive seen on youtube/from friends, it seems fairly simple. Could someone please give me details on what my max overclock would be and whether i would overheat ect.

Components im building with:

CPU: i7-950 @ 3.06Ghz
CPU Cooling: Corsair H70
RAM: 6GB Corsair CL7 1600Mhz Dominator GT RAM w/ airfan
Motherboard: Asus Rampage III Formula
Case: HAF X


Thankyou!!! :hello:

Well you won't experience any problems with any of that, as long as you don't use the stock cooler. If you haven't gotten the H70 don't get. The H70 is not worth what they priced it to be. Even a 30$ HSF like the Hyper 212+ with an extra fan could cool a 4ghz 950 easily. I mean even though the Hyper 212+ is loud. The H70 is just as loud, it's not exactly a quiet water (fake) cooling system if you will. Now watch your power consumption rise though, I'm pretty sure the its around 150 watts over the tdp, so the original is 130, it's around 280. For 4ghz.

alot of people have told me to get hyper 212 + ect. but i am aiming for a computer with the least amount of moving parts and quietest cooling. I'm getting a Corsair HX-1000W, will this suffice for the build?

o.o whats your VGA card? Unless your SLIing 480s, you shouldn't need 1000w, especially one that has a high efficiency of 1000w. You'll AT MOST need something like the XFX 750w Black Edition, or something like the 750 NZXT Hale90.

Also, the H70, thats 115$ if I remember correctly. It's not that quiet. You may think it is because it advertises that it is "Water cooling" Its not. Its "fake" water cooling, with a real loop its much cooler, and quieter. The H70 is actually really loud. If you want quiet just get the Hyper 212+ That'll run you 30$ + two Noctua 120mm U.L.N.A fans which are 15-20$ total would equal only 70$ which is still cheaper than the H70. That or you could get the Noctua NH-U12P-SE2 Both are great.

As you can see, the review states that when you add the 12P's so the two noctua fans, its significantly quieter.

Also, didn't want to edit.

Check the dBa on low and high speed for the H70... It's equivalent to the stock cooling on the Hyper 212+.

If you want quiet and good performance, the Noctua's are the way to go. Or just put noctua fans on the hyper 212+ as I said.

1/ I know h70 isnt true watercooling. I like it because its close looped, all in-one pack that i can easily install.
2/ Would the HX-1000W be good if im getting AMD6970 *2 way crossfire?
3/ could someone please answer the threads topic, what is the max overclock do you think i can get, i know you cant be EXACT but maybe a 200-300Mhz range. (HAF-X w/ 4 case fans /H70) :D

Your guess is as good as mine... the 6970s tdp hasn't been released

Huh, still going with the h70 :p  Well... 4.3 or 4.2 is what I've seen, some at 4.4.
