based on amazon reviews ordered the coolermaster 212 for i7-6700k

[goto35]

what do you guys think? Building a pretty crazy computer (i7-6700k, crossfire 290x, samsung 950 m.2 sd)

And only spending $30 for my air cooled fan. Will slight overclocking be fine on it?

 

[||Console||]

From what people are saying ~4.2 YMMV

 

[ATMINSIDE]

You'll get it to overclock some with the 212, I'm assuming you bought the EVO?
Just don't expect miracles and you'll be happy.

I went with an existing NVidia 980, but basically just built the same thing, with the EVO. I'm running 4.5 at 1.32V with idle in the 30s, load in the 70s. I stopped at 4.5 not because of heat, but I sort of lost the silicon lottery on this 6700k - for 4.6 I have to jump to at least 1.4V, and 4.7 looks like it's about 1.45V.

Depending on the CPU, 4.5GHz sounds about right. The 6700K is a 4.2 GHz chip stock.

Yeah, I'm fine with it, although do get a little envious of the people reporting 4.8 on less than 1.4v. But as a practical matter, doubt I would notice the difference day to day.

What stress test do you use for 4.5GHz 70s with a 212 EVO?

Prime95 on 8 threads for a few hours. It was high 70s over a couple hours.

 

[EarthDog]

Which test in P95? Small FFT? Blend? Large FFT? They are significantly different.

 

[wingman99]

Wow when I upgrade I'm going to save some money and go with 212 EVO, l wood like to run prime95 at 4.5GHz with that setup.

Just default Blend. Was just wanting to heat up the system and see if it was going to error or crash, not trying to be particularly rigorous.

 

[EarthDog]

That makes sense on the temps. Small FFT will only test the CPU and it gets much warmer.

I'm actually amazingly impressed with the 212 EVO (and the earlier version, as well.) I've got a Swiftech H220 sitting in the closet that bought me a couple C, but was noisier. And I've used TRUE Rev C's push/pull before that.

To be honest, I just bought a 212 for my previous build to get it up and running, while waiting for the Swiftech, and then switched them. But the pump failed, so had to jump back to the 212 while getting the H220 fixed, and then never bothered to put it back in.

While a great cooler for the money seems like you did ok.
In future I would look somewhere else for a review other than Amazon ......

That is how I have always tested Default Blend, it is good to see that the 212 EVO does so well with the i7 6700k, most of the people that are frequently here won't even touch prime95.

I know the 212+ did fine with sandy bridge at 4.7GHz.

Ok, so you got me curious. Just did a quick 10 minute run.

HWiNFO64 - max 79/73/79/73

HWMonitor and RealTemp - max 85/79/85/81.

Although I'm not able to get any faster under 1.4v, I think 4.5 at 1.32v is actually pretty nice!

You guys really should do a Small FFT test, most video editing/fold/seti software and some games do comparable temperatures.

I did, see reply directly above yours.

Oh 4.5ghz 1.32v ? Not bad at all for a 4 core my bad thought that was still blend
