Just to back JHautz up, that little Tekin bugger worked very well all day. We took temps pretty religiously all day and the temps he is reporting were on point. As a comparison, I was running a MMM with No Fan and the top of the case cut off with plenty of air flow into the body. Neu 1512 2.5d with a 4s 5000 running 20/46 (about 39 mph tops). I was getting temps up to 160-170 pretty consistently through the qualifiers and practice. After the 15 minute main I pulled the car off the track and the MMM was 195 degrees.

Very impressed with how that Tekin performed.
