Cooling Why is it not recommended to overclock with a low profile cooler?

[ng4ever]

I know stupid question. Sorry.

The cooler has low mass and very few heat pipes, it simply isn't good enough for most overclocked CPU's

Thanks will it ever be possible to overclock with a low profile cooler ?

Depends on how far you're willing to go :3

What processor do you want to cool?

Ouch, that's hot. You'd need something like hermes, maybe a thermalright full copper AXP would get you a light OC though

I tried that but switched to a Scythe SCBSK-2100 120mm Sleeve BIG Shuriken 2 Rev. B

Probably already at nearly the limit of low profile coolers then

Ok but then I saw this:

Hahahaha. Well that is a 90+ watt chip. What is your definition of low profile? Sub 45mm wouldn’t do it but sub 60mm could with a bit of airflow.

The HSLP is smaller than the shuriken

Ok thanks which means ?

That big shuriken could handle a bit of oc if you delidded. I had one with a 6700k ( not delidded) at 4.5 in a silverstone rvz02. But I know kaby runs a bit warmer than sky lake. But yeah, at these sizes they can only handle so much heat. What case are you using?

I fear my only option is water cooling Oh well. It is ok. I just prefer not to use a AIO.

Could you mount a 120x25mm fan to the shuriken? That would help quite a bit I’d imagine.

I did. Actually a 140 or 150x25mm fan just earlier!

It has mount holes for 120mm! So it worked!

Not sure if it helped a lot because I forgot what temps were before with the 120x15mm fan lol.

I know in Prime95 2.6.6 it only went up to 81C

 

[ng4ever]

Also one more thing should the air be blowing onto the heatsink or away ?

 

[loader963]

Well if that’s it in benchmarks, surely you are 15C cooler in normal uses. Why not run a mild oc and see how it does. If you have hwinfo64 or another sensor program you can monitor your temps and make sure you are safe.

More mass = better OC

 

[loader963]

Blowing down onto the heat sink would be optimal I’d believe.
