My new build is running warmer than I would like. motherboard socket is amd3. Under torture it runs in the 60's and this is while the computer is sitting on top of my desk which it will eventually be inside the cabinet. I planned to get a 212+ but measured and my case doesnt have room for it. I want a cooler that will fit and keep my CPU at a reasonable temp will in a cabinet. Any advice on one for $40 or less that will do the job?
