Hello, I got a 1,2GHz Sonnet Encore ST Single CPU, which came without cooler/fan. The former owner had not put thermal compound on it and it overheated (at least you could see a loose molten piece of metal covering over the chip) and I got a cheap PM G4 for parts. I installed the CPU to test it and it works fine so far, but I wondered, if the stock G4 CPU Cooler would cool it sufficiently. On the net I read that Sonnet first issued a version without fan and later added a fan to the newer charges. One User said he has running one only with a stock cooler, without fan, but he thinks it is working because it is the bigger piece, that came with Digital Audio G4s. Mine is an AGP, with the L-form cooler. Now I am wondering, if it is really possible to use the CPU just with the cooler (since Sonnet did sell them with fans later, anyway). If so, what would be a good, silent fan, I could mount to the stock G4-cooler (I already have an idea, how I could attach it to the cooler). (Another idea was to DIY a copper cooler as a replacement) I read about case fan replacements here, but I did not find anything useful for a CPU http://forums.macrumors.com/showthread.php?t=1232695 Any ideas?
