Just to share I finally switch out the backplate to the Thermalright one. It helps about 5-10c! Previously I underclock and undervolt it by setting PL1 to 125w and PL2 to 180w before it gets thermal throttling but now it can go up to 200-220w for PL2! Not that it matters much in day to day usage or gaming but just good to see the temp gets good and since the backplate is not that expensive. But I still couldn't get it to 253W cause it'll get thermal throttling half way. Room ambient temperature probably about 26c since no aircon.

Backplate? You mean the ILM bracket holding the CPU rite?
Yeah similar to my result too, reduce by 8oC https://forum.lowyat.net/index.php?showtopi...ost&p=110531724

Your using fishtank case so temps will defo be higher cuz airflow in these type of cases is poor.

Ya that's right. Was thinking if it's placebo effect until I finally made the decision to do it. So just want to share here again to let others know it really works haha.

But I didn't do it as meticulous as what you shared in your thread. I just screw it tight and that's all lol

Haha cuz I heard its high risk to screw RAM stability due to wrongly tighten down with unequal pressure, having to redo RAM tuning & testing, stability issue whatnot. Hell no I will go thru that after 2 weeks of RAM tuning. Also I want to make sure doing properly will give it best chance to work and doing it methodically isnt that difficult once I understand the concept. But congrats on your results too!

Now I wonder if anyone will do for LGA1851 as well haha.

LOL if I want to change CPU next time I will skip Intel for a while until they fixed their shit.
