I have an old Pentium comp that is overclocked at 200 something mhz I dont know how fast it is because, when i first got it i turned it on and the power supply blew, so im gonna get another one, I removed the fan and heatsink and removed glue off the Pentium i like the way it looks without the fan and heatsink on it. Cause i like computers without cases well some , i like this one because the mobo is small. Anyways my question is do i need the heatsink on it to run it again without overheating, I know its less convinent but i was planning on getting a fan to blow on it at full blast to cool it , I had an old 486 overclocked to 50mhz its normal speed was 25mhz so I took a window fan sat it on top of it set it to full blast and it kept it artic cold. So is it ok to run just a fan? I know its a dumb question but i love going to extremes!
