As much as I can.The quark overheats if I push it to hard ,surprised :),for more then 10 minutes.I did a minor heat mod,and added caps, that helps,but it's really just a temp to get me through till the mmm is available.I added a heatsink to the Medusa after the first run with it got up to 160,but i also had it geared higher at the time.Since then I've never seen it above 150.Today I ran for about 20 mins and it was 128.
