Hello there! I'm thinking into modding my CoolerMaster Cavalier case because the case gets too hot! currently I have the classsic rear 120mm fan, and a 80mm front fan ( default coolermaster ones ) and a 60mm side fan. the problem is, with my actual overclock ( wich is not that strong.. just 250 FSB and a Winchester from 1.8 Ghz to 2.25 ) it gets preety hot thanks to my new MOBO wich is a Nforce 4 , and my new videocard ( X850XT PCI-E ) The temp can go up to 60 ºC if I use it with my case closed (for protection I have the case open atm, and the cpu temp is always lower than 36ºC on idle and 49-52ºC on full load. So the question is: What Kind of Fan should I add to my Cavalier so more air flows inside my comp? should I mod the case door to add a window, and thus cut it for bigger fans? ( the actual door is pure aluminium and only has room for one 60mm fan and my actual one sucks) Note that Noise is not a problem since I Have a profound hearing problem ( Ie, Deafness ) so recommend me some FANS, BRANDS, and MINIMUM RPMS or TYPE OF FINS in the FAN. Images of Cavaliers: Inside view, shows the 120mm Fan Side view, shows the Aluminium Panel and a 60mm Fan slot.
