After disabling power limits in my previous post, I needed to improve my cooling a bit more, as I was still hitting thermal throttling when on full load. So, I performed the below mods to my computer. :-
My PC now idles at 28 freaking degrees.
This thing can now cool 30W indefinitely at just 73 degrees. the peak of 75 degrees was hit while the CPU was in short PL which is basically uncapped. The power consumption shows 15W because of the IMON slope, the actual consumption is 30W. Just check the frequency for proof, at 15W this CPU cant cross 2.7Ghz . I can probably reduce the imon slope further and just completely unleash it and it would still be under 90 degrees, but I do gaming on this PC, and its never gonna use more than 30 W when using the very underpowered MX150. Regardless, its really impressive what a few hours of your time can acheive. This applies to anyone looking to get more out of their U-series processors. If you are looking to do something similar, I would mostly just recommend the cooling pad and the liquid metal(be careful using it, you can end up killing your pc if you aren't careful), and the undervolt, along with the cooled VRMs, incase your VRMs aren't cooled by your heatsink already.
- IMON Slope set to 50 % (Significantly reduces power limit throttling by changing TDP long to 30W)
- Undervolted -150 core, 115 cache (Allows it to reach maximum frequency using only 32-34 W)
- added thermal pads between keyboard and motherboard.(decreases temps by about 2-3 degrees, check brad's hacks for more info)
- Thermal grizzly conductonaut liquid metal on CPU(easily reduces temps by about 5-10 degrees)
- connected CPU VRMs to heatsink with thermal pads. (eliminates VR TEMP throttling. This only occurs, because HP decided not to cool the VRMs at all. It is literally no where near the heatsink. I just cut a thin thermal pad strip from the VRM to the heatsink)
- salvaged heatsink from another laptop and stuck it on top of the main heatsink. (While I expected this to be the biggest temp gain, surprisingly it did very little, and therefore I ended up removing it.)
- Some random cheapo cooling pad.(another easy 3-4 degree drop)
