hey guys

here are the new parts i want to install to build an extreme PC


MB : asus extreme 79
CPU: i7 3960x
case : cooler master sniper SCG
water coolig for CPU : crosair H80


already installed parts


GPUs : zotac 590 + zotac 560TI for physx
ram : 24 GB DDR3 1600mhz KINGMAX
PSU : odin 800w






so what i want to know is how far an i OC i7 3960x with crosair h80 ?!!


thanx

What have you read so far? You should easily be able to hit 4.2.

An H80 will have a hard time cooling a 3960x at stock!

When overclocked to 4Ghz or higher the 3960x dissipates more than 200 watts of heat

You are going to be dangerously close to the limit of your power supply, be careful

so what cooler should i go with ?!!

i got a very good air flow in the ase

4.0 = 200w @1.35v. 4.2=209w @1.35v so that's about right on but will depend on actual volts needed for stability.

Stock TDP is 130w so stock cooler (or any cooler for that matter) should be fine. However, I wouldn't consider even a good air cooler or an H-series cooler for overclocking this chip. You really don't need to OC it at all- it's incredibly powerful as it is at stock speeds.

This isn't a CPU speed race anymore; it's a processing of threads per clock cycle race. Upping your CPU clock speed will do little more than just give you higher benchmark scores; nothing more.

Mine hits about 220 watts at 1.31 volts at 4Ghz but that includes all components. The IA cores alone hit about 190 watts.

Unfortunately there is no stock cooler for the LGA 2011 chips and Intel's reference cooler is actually a water loop

so do you recommend OC using h-100 + 4.ghz ?! is that safe ?

H-100 isn't that great of a cooler.

The H-100 isn't horrible. It's sufficiently more compact than a custom water cooling loop and easier to install than any air cooler. The lack of a reservoir means that the water heats up fast and reaches equilibrium faster

I've got a rock solid 4.4 with a NH-D14 2011 with decent volts, I've not even attempted higher on air.

You can have a watercooling loop without a reservoir at all and it would still hand this thing it's own behind. It has nothing to do with the volume of water in the reservoir (or no reservoir)- all watercooling tests are done with the water at working equilibrium anyway. The pump flow is horrid and the only thing working for it is the 240 radiator.

The H100 isn't horrible; no, I agree...but not worth the money when you can buy some great intro watercooling kits for only a few more $$ and cheaper air coolers perform on-par with it. Being 'easy to setup' isn't worth the price premium and lackluster performance.

It's essentially the same thing as the H100.

so i should go with h-100 ?? since it's much cheaper


but i got a word from another overcloking forum that extreme water 2.0 is way better than h-100 !!!


to be honest al i want is a good water oolig item that is solid and can get me to 4.4ghz at max i'm not razy about OC too much

but i'm afraid it won't fit my case cooler master sniper SCG

Much cheaper than what?

What forum is this? I'd be curious how they came to this conclusion- they are almost identical coolers.

Stock speed for your CPU is 3.3? A 1.1ghz speed change would be a 'crazy OC'. I think you are somewhat confused on what you really want to do, here? Do you even know if your chip can get to that speed and sustain? Do you know how to overclock, or do you just use the fancy buttons and GUI?

I think you are missing the larger issue here- why do you need to OC a 3960x if you aren't even sure how to determine effective cooling for the chip at those speeds? What does the CPU not do at 3.3ghz or even 3.8ghz that it needs to run at 4.4ghz? I understand the desire to overclock, but what is the reason behind it? I'll state again:

i have to admit that i'm not an expert in OC but i did OC i7 950 to 3.88 safely with cool master v6 gt



however what i want is a cpu that can handle 1080p rendering operations smoothly and fast

i'm not looking for 4.4 or crazy about it i'm just saying that i want to OC to the safest spot with h-100 or water extreme 2.0 if ever bought it

H-100 and that Thermaltake unit are almost exactly the same...if not exactly the same. Performance will be identical down to a fraction of a degree difference.
