An our ago ordered that kind of turbo blank from ebay, two pieces 30x30 cm. The man says that is thermotec. Also i changed the fans setup, in front of the rad now i have an 12" fan and an other 9". Behind the rad putted the other 9" to suck air. Beforer this after ten minutes idlins fans didn't stop at all. Now they working a few seconds and then stop2. I will go for a ''full boost round'' to see if there is any defference
