fanless cpu cooling

[newgeneral10]

I will be building a freenas box using a i3-6300 processor.  Will it overheat if i use a hyper 212 evo and take the fan off?  There will be some case fans in the 4u server case and the cpu is rated at 51 W TDP.

uhm, i generally think if you want to go fanless you need something way bigger, like a dark rock 3. i wouldnt go fanless tho, expecially with the cpu

[TechRicalx]

I don't think so if the fans are close and there is a positive air pressure, sure it will not overheat.

you're going to want a nofan cooler, the biggest tower cooler you can find, or a water loop with infinite water.

So do you think I should just go with a "silent" cooler?  How about the Cryorig h7?

[Bcat00]

If i remember, zalman has a massive cooler that is meant to be passively cooled. 

Then again why not just set your fans at 300rpm instead?

[ashypanda]

a H7 will be fine, even something like my shadow rock slim, can keep my 6600k cool with the fan spinning at 350rpm, and no case fans running.

Try it and find out.

Id rather not just burn up a cpu for the sake of "finding out"

They have temp protection.

It ill throttle itself if it gets over 90something degrees.

It definitely shouldn't overheat with the 212 evo fanless.

 

Even if the things do (somehow) get to 100 degrees, system will shut itself down to prevent damage, rather than melting down.

 

So fell free to try it.

I'd rather go with an overkill cooler + fan.

I am cooling my NAS-CPU (i3 6100) with a Dark Rock 3 with the included silent wing fan. Normally you cant hear a thing when its at 300rpm. But if there is load on the cpu it can ramp up and keep it cool.

Also if your are planning to have case fans anyway, that one fan at low rpm wont make a difference at all.

With 51 watts the Zalman FX-70 will be perfect for you (does it fit in a 4U case?). It's not to expensive and works great.

Sadly they stopped production some weeks ago, but there should still be plenty of stock.
