i7-6700k high temps with Cooler Master Nepton 120XL

Beleg_Jr · Nov 9, 2016

Hi,

as the title states, I get high temps trying to cool my i7-6700k oc'd to 4.5ghz w/1.325v cooled with Cooler Master Nepton 120XL. I get 80celsius plus while gaming...

I'm thinking I could go with a lower vcore,
and I've bought CoolLaboratory Liquid Ultra. Because I think that the paste that my supplier applied can be a source of error.

I've read threads about delidding, but I can't help to think the "gap" is there for a reason!

I'm aiming for around 70degrees celsius if possible with my settup

regardless of what you are aiming for, you are playing the silicon lottery. The only levers you have are the cooler, the TIM, the voltage and the speed.

80C for 1.325V is normal

EtnoNyt :

So you're saying that a delid is my option if I want the temps down?

I'm fine with the temps, but I get occationally a bluescreen here and there.
I managed to get my 1070 FE temps down from 80 to stable 70 by just manually setting up a more aggressive fan curve.

I was hoping to somehow lower my cpu temps a bit too, or must I downclock some... I rly dont want to delid my cpu

Update: I'm also wondering if the "CoolLaboratory Liquid Ultra", will make a difference or not. Or if I should replace Cooler Master Nepton 120XL with another cooler. In that case I cant fit a double radiator unless I front mount it!!

Beleg_Jr :

delid can give you a significant temp drop, but you have to take the risk.
set CPU fan to higher RPM can help, but will generate a much louder noise. This is the safest and cost effective way.
applying the liquid metal on lid can reduce the temp by 2~3C, but I believe this is not what you are expecting.
you may get 5~8C lower temp by a 240mm/280mm cooler, as long as your case can support the big radiator. Another 120mm cooler won't help a lot.
the most expensive solution is custom water loop.

My case can support a bigger radiator, but I'll have to front mount it then.
I'm instead considering to just throw the CM Nepton in the garbage and bying Noctua NH-D15!!

I changed the Thermal paste #Problemsolved!!

Idle temps are now 20celcius, and load temps stable at 60degrees (40-60 used to be my idle temps)
