Last year I had no problem. When the cpu fan lost the high speed it was replaced with a different model which I supposed was *New* or *Upgraded*. Anyway it dosent work as well. I did shave about 3 deg by removing the offside panel so there is plenty of room for air to get out. Now I shutdown if room air goes above 85 since it is getting time for outside to go above 95 the air conditioning will have to be on so that problem should be solved. My case has 6 fans 3 in and 1 out, 1 cpu & 1 for mobo chip. Liquid cooling is sounding better all the time. -- Regards; Hoyt
