I noticed that the latest Lunatics Intel GPU app for MultiBeam v7 has increased GPU utilization to the point that my i7 laptop fans spin up quite a bit to keep up. This is good news for the efficiency of the app, but bad news for me on this machine. That laptop sits in my office, and I use ThrottleStop during the day to adjust the CPU multiplier to a level where the fans aren't too loud. Unfortunately, I'm unable to underclock the Intel GPU (I tried using the Intel Extreme Tuning Utility, but Graphics Tuning is locked) so I can't really run the SETI Intel GPU app 24/7.

The Einstein Intel GPU app grants more credits and runs a bit cooler, but uses more CPU... I'll stick with that on this machine.
