Why is the cooler vibrating is it loose? The levers secure the cpu, the cooler should be fastened to the motherboard on four corners by a pop in type of fastener. The X plate with the new cooler would go under the motherboard for the cooler to fasten/screw into. The Xplate should also have an insulating gasket to prevent it from shorting out the underside circuits of the MB
My CPU cooler on my P4 vibrates on bootup and then quiets as long as cpu is up. I ordered a Masscool 8W0141B1M3G / Socket 775 / to replace when it gets worse. I see there are 2 release levers around existing cooler. Replacement comes with 4 twist down screws and a black ?X? plate. Do the 2 levers release the P4 or just the cooler? What is the "X" plate used for? I?ve never done this before, so any ideas are welcome. Thanks!
