got a Celery PPGA 400@600 and sometimes 618, but the temperature is some 50 degrees Celsius after 15min of Q2demo. I use Titan K635T, which is 35mm high with ball bearing, but it doesn´t seem to be enough. Do U think it is dangerous for the CPU and how can I cool it better? Thanks Tom
50c is normal(though not healthy)if you don't have a good cpu fan and overall case ventilation. When I had my Cel366@550, it use to run up to 55c. All I had was a little heatsink and ballbearing fan. So I loaded my case with fans(7), got myself a dual cpu fan and now it's down to 35c @606. I recommend you purchase a higher quality cpu cooler and don't forget the thermal paste.
