Anyone else undervolting their alpha for lower temps?

Hello Everyone,

I just got my LPA 864 back from an RMA. (You can see my other post.) I am working on trying to reduce the heat output by undervolting the CPU. I am just wondering if any other LPA owners are trying the same.

I have been using the Intel Extreme Tuning Utility Win10 and GeorgeWhewell's Undervolt CPU in Ubuntu 18.04 to do some simple changes. I was able to reduce the core voltage offset by -0.06V and maintain stability in both OS's.

In Win10, I have used the Intel ETU's for benchmarking. Using the default setting (no voltage changes), the bench mark resulted in a max temperature of 80C with a score of 424. Lowering the core voltage offset by -0.06V resulted in a benchmark score of 422 and a max temperature of 73C. (Not a bad start)

Has anyone else tried undervolting their LPA? I was just wondering before I start looking at the other voltages and timing settings.

(I did search if there was another postings on the subject. I did not find any. If there is, I will just redirect to that thread.)

Good Luck,
SpareADime

This is a very interesting topics. I've mentioned this idea with our product team. At the same time, I did some quick research for this topic considering that LattePanda Alpha use the same chip solution as the Surface Pro, which is the Intel Kaby lake 7y30 on this generation!

Hi SpareADime

I replaced the thermal paste on mine with Noctua NT-H2 (non-conductive) and it got me as much as 5 C cooler depending on the test. Definitely worth a look.
