7700k idle temps after delid

I just did my first delid on my i7 7700k and haven’t gotten over 71c under load. The question I have is I don’t notice much difference in idle temps after the delid. Is this normal? I am around 29-33c  idle.

Yeah, it's normal for idle temps to vary much less. For one because heat dissipation is a lot lower at lower temps, and also because the computer is slowing down the fan automatically when at low temps unless you have your CPU cooler fans set to a constant rate.

We have a NEW and GLORIOUSER-ER-ER PSU Tier List Now. (dammit @LukeSavenije stop coming up with new ones)

You can check out the old one that gave joy to so many across the land here

Also, remember that the CPU CAN NOT idle below ambient temps.  Even close to ambient temps.

When you consider your room is probably 20C.  The extra 15-20 degrees is nothing.

Thanks and I also noticed there was some differences in core temps while under load.

 

core 0- 72c

core1-59c

core 2-67

core3-65

 

 

is it normal to have 10+ degrees difference?

Can be if core0 is doing most of the heavy lifting and the rest is just supporting.

Are those decent temps under load for an I7-7700k after delidding?

The difference in core temps could also be related to bad TIM application. I am assuming you did a good job painting the DIE with the LM, but you probably don't have the best TIM application between the IHS and heatsink.

Also temp at idle will change very little with a delid. The process of delidding is to help the thermal transfer between the DIE>IHS>Block. So at idle when there is little load this doesn't really do much, but at load it makes sure the heat can move away from the chip and to your cooling solution faster which is where you will see the most gains.

 

I would reapply TIM between your IHS and Heatsink and see if your core temps get more consistant. If not then it could be an issue with your LM application, but it isn't a huge issue either way as the temps are still well under thermal limit.

Thank you! I will do that. Yeah I am pretty sure I did fine with the LM and the Lm on the underside of the IHS. I will reapply and see what happens.

 

Thanks!

Stress the CPU with something and then check what the temps for all cores peak at and make adjustments from there.  At stock voltage and speed, after a delid, you should stay under 75 degrees no matter what.

At least my 7700k does with a Noctua D15.

I am sorry I should have clarified. Those temps are under full load stress with Prime95. The highest I got was 72 degrees I was just concerned about the 13 degrees variance between core 0 and core 1
