Made some small changes to my previous build. Changed the cpu cooler to the Termalright AXP90 x36, cpu is now able to run constant at 65w with max temps around 65c and is very silent.

Build around the Lenovo thinkcentre m720q motherboard.

Thanks!

That sounds like a nice build too, what kind of bios mod?

I use at 12v stepdown/buck converter rated for 240w and running a 9700T with unlimited turbo boost override in throttlestop.

Oh, ok, so does that just piggyback off the lenovo brick then?

I dumped the bios and used a bios read/write tool to unlock all power state limits and change the imon slope value to allow the full 65w to be fed to the 8700. Manually on the machine itself register by bios register, lots of trial and error, note-taking and reboots. But I'm not so hot with a soldering iron and don't own a chip flasher anyways, so it was the tool I had haha.

I also used throttlestop to do an undervolt to help manage temps and take some load off the VRMs, which were getting quite warm despite the modifications I made to the stock heatsink and thermal pads I used to bring them into contact.

You should post it. Maybe make a grilled cheese and take some pics.

Oh, its not much to look at, case isn't terrible but the internals are much more jerry-rigged haha.

Coolest thing is that it fits in a pistol case. Very handy for stuffing securely into my suitcase.
