CPU cooler - OC'ing i5-4670k

redblade904 · Jul 2, 2014

Hello there, I was wondering what would be a good air CPU cooler for a i5-4670k which will probably be overclocked at 4.4ghz. Could I get some recommendations for a good cooler that will be compatible with my build/case for around £30 and also a £50 recommendation.

Here is my build:

Well although I haven't got one myself the Cooler Master hyper 212 Evo has great reviews and people seem to get great results with it as long as there is enough airflow threw the case. Anything from Noctua will give you great cooling as well really, you can't go wrong with their products but just check the height of the cooler and then see what you can fit in the case, it will say on Corsair's website so it will be easy to find. The Cooler Master cooler fits in the case, just checked but you'll have to check for yourself about any Noctua ones

A very good build.
The value cooler is easy: cm hyper212

A mid range cooler is harder Noctua NH-U14S
a bit over your budget:

Since each cooler comes with good paste, you can omit the as5.

The i5-4690K is now available at the same suggested retail price. At similar price it will have better thermals.

Hi, I have already purchased the parts for my build so I will be sticking with the i5-4670k and the AS5. What temperatures do you think I would get with the coolers you posted geofelt? Remember I will probably clock to 4.4ghz.

Cheers.

How high you can clock is determined by your luck in getting a good bin.
As you increase the clock, more vcore is needed for stability.
Once your vcore gets to about 1.25, two things happen.
1. Heat rises exponentially.
2. Damage to your cpu increases.
The high clocks you hear about are often at 1.3v or higher. That is not prudent.
Yes, a better cooler will let you operate at 1.3v or even higher, but do you really want to do that?
My guess is that 4.0 is very likely. More than 4.4 at 1.25v is not that likely.
Not to worry. haswell @4,0 is a very competent gamer.
Take what you can get and enjoy.

I would buy the noctua for two reasons:
1. Mounting and quality is superb.
2. A 140mm fan will be quieter at load than a 120mm fan.

Would this be compatible with 2x tall corsair vengeance and also what temperatures do you think I would get at 4.4ghz? I know I may not be able to reach this but I just want a rough idea of the temperatures.

Cheers.

It depends on the voltage it takes to get to 4.4.
I might guess that temp will be 80c. with a good cooler.
