Official Guide: Putting a P870TM1 CPU heatsink into a P870KM1 (P870KM to TM1 partial conversion)

I will try and save you a bunch of time and headache. Going bare die wont help the temps but in fact increase them.
Even if you fix the vrm height offset that the heatsink has, you will create a hotspot without the ihs. Meaning instead of heat being spread mostly cross all 4 heatpipes, 2 of them will do most of the heavy lifting.

 

The CPU VRM. If you lower the main part of the heatsink by ~3mm by removing the heatspreader, it won't sit flush due to inductors and standoffs currently sitting within that 3mm zone.

 

Is there another VRM it contacts?

 

I feel like I need to drop my direct die idea project...

 

Or you could straight up solder the ihs to the heatsink and have direct die. But that depends on how bad you lost the heatsink lottery.

 

My biggest issue at the moment with my 870km1, that the 144hz IPS screen are flickering... I dunno if it is gpu or mb or what problem... I have changed the cable 2 times and did not solve it... the 120hz QHD or FHD panels work fine with gsync... any idea for that?

 

now wouldnt that be something... a clevo reseller binning heatsinks for each LGA/MXM clevo machine they sell

You forgot binning the Cpu Bracket

 

Oh man, I remember how much of a nightmare that was on my p870tm1! Temps were around 95c no matter what I did because the heatsink rested on that retention bracket instead of the ihs.

So I just removed it, good riddance!
