Overclocking a i7-2600k in a Fractal Design R4

[Kyroshic]

I was thinking about buying a closed watercooler that is of course premade already. My criteria is noise, and efficiency of the water cooler.

 

System Specs:

P8Z68-V PRO

The i7-2600k of course

Gigabyte 7950 3GB

8 GB of G2 ram

Corsair 500CX

2 Fans that came with the case in the front intake

1 noctua exhaust 

 

During games the cpu runs about 72-78 degrees Celsius (with stock fan) (about 1677-2000 RPM)

The temps are fine for now but if I over clock there might be a problem so yea..

Idle is 35-36 degrees Celsius (about 1170-1190 RPM)

Well I got an R4 with a 4670k. I overclocked it to 4.5Ghz @ 1.25v and cooling it with a H100i with two stock fans on it. I get 56°C as my hottest core when stress testing. I got a total of 3 exhausts (including the 2 rad fans) and 2 intakes in my R4. There is place for another intake in the bottom of the case, I can give you pictures if you like when I get back. My H100i runs at 900rpm, under my table it's silent.

YES YES pictures plz and what Mobo is it

You're running Sandy Bridge. Those chips only run hot if you have the crappy stock heatsink or if your room is too hot. Any decent aftermarket cooler + premium TIM will keep the cpu running cool. You don't need something uber expensive to cool Sandy Bridge, just something nice that isn't stock.

Some advice, I'd recommend buying some fans for the H100i if you're getting one such as SP120's but make sure to get the 4-PIN because I made the mistake of getting the 3 pin but if you want to use corsair link to control them, you need 4 pin hence why I'm using the stock ones and have the SP120 as an exhaust.

I'm going out now so I'll speak to you later!

[Kyroshic]

I have a stupid question why would I have to replace the stock fans of the h100 if your system is silent enough.

Btw thanks for the pics, but did you have to do any modding for that h100 to fit?

[Kyroshic]

And one thing I have to ask could I undervolt my cpu and over clock the frequency to make it run cooler but more performance?

I believe you cannot undervolt sandybridge. I recommend fans because these do make a buzzing sound now and then because there are no rubber gromits around them but other than that, it's perfect. The R4 can fit a H110 without modifications so no, I did not mod my case in any way, I can infact show you where it's screwed in. (picture provided). There is a gap left on top because the R4 supports a bigger rad.

I just overclocked my CPU to 4.8Ghz @ 1.325V and got these as my temps; I may try to push 5.0Ghz @ 1.375/1.4V

Nevermind, 5.0Ghz @ 1.375 bluescreen'd, don't wanna push my CPU further so I'll settle for 4.7Ghz @ 1.325v

Thank you for your recommendation and support for my topic, and you made my desicion more clear.

Btw I have some extra rubber grommets from the hard drive slots, would that suffice? And your overclocking skills are beastly man.

[Kyroshic]

Oh Yea do you think a h100i would fit? or are they the same size.

 

PS never mind

One question is my gpu being bottlnecked by cpu

stock h100i fans quiet? ngrplz...

In the quiet profile, they're quiet enough for me. Different people are different.

It will be running a fair bit slower at stock then if you had a decent oc on it, but it certainly isn't bottlenecking it unless you have more than 2 or 3 of them.

the whole idea of overclocking is finding the lowest amount of voltage the CPU can

use and be stable with the highest amount of multiplier to produce more processing

power.

 

new to overclocking it is best to find what the voltage used on load and add multiplier

to achieve stock voltage overclock. another is to lock the multiplier to stock and lower

the CPU voltage until instability is found. my 2700K was 39 multi on 1.085v versus

the stock 39 multi and 1.275v, this lowered my operating temperatures on stock by

15° (72° to 57°) under OCCT load. doing this shows what to look for, how your CPU

functions and needs voltage and what temperatures do when more voltage is applied.

Yea so I found out I really wont get much of an improvement for gaming at least, because my cpu is not bottlenecking my gpu. So everything is fine, I dont have to oc my cpu.

Thank you anyway man means a lot.

no..

Thank you for informing me with all dat knowledge!

And it isn't too necessary for me to oc my cpu right? Or even have an after market cooler.

no you don't have to overclock, but it is free. using an aftermarket CPU cooler is fine,

but wasteful as the OE cooler is plenty for stock clock running.
