    ok so i have successfully installed the cpu however the temperatures do not seem all that better.... before on idle with the stock cooler using speedfan the temperatures would read around 40-45.... and with the cpu cooler they have only seemed to decrease by 1 or 2 degrees.

    Whats going on shouldn't it drop it further?..... and also i realize that with some thermal pastes you need to wait for a few days for it to really work so to speak... but still i was expecting at least 5 degree drop. I guess i should also take into consideration other variables like ambient temperature, airflow inside case, number of fans etc.

    But 2 of those i think should be fairly good... i have 5x120mm case fans and my cables are managed fairly well inside case however the temperature today has been shocking.

    I dont know the ambient temperature, but going off the readings of a weather gadget it was supposedly 35C in the day about 25C now when i measured the temps of cpu.
    If you could tell me if those temps are bad for a brand new cpu cooler or if i am worrying too much... and if they are bad how I can improve them.
    Thanks in Advance.

    PS: Iv attached 2 screenshots of the temps on idle and at max load with Prime95 (after a couple of mins):

    How exactly are you case fans setup? Which one(s) blow air in, which out etc. Having more fans doesn't necessarily increase cooling efficiency, in some cases more fans will actually decrease your cooling efficiency!

    Setup shouldn't be too bad although personally I don't see the need for that many case fans. I used to run an overclocked 8800GT graphics and Core2Duo cpu (no OC on stock cooler) with only 1 intake and 1 exhaust fan, never had any heat problems.

    So, next thoughts is possibly too much or too little thermal compound on the CPU cooler? What type of compound are you using?

    just the paste that came with the cooler.... so coolermaster and concerning too much or too little thermal compound that could be the issue...... i didnt apply the paste myself my friend did it (has more experience than me and i was afraid i might do something wrong)..

    OK, unless I am missing something here we have no idea what hsf you installed AND no idea what cpu you have installed.
    53C under prime95 is a pretty good temp however do post the exact cpu you have installed so we can see how hot it is running.

    Those temps are a little high however not overly so. My 965 overclocked to 4gig is running @32C right now under no load. It will get up to 55-58C when running prime95.

    One thing to be sure to do when using that type of cooler. Install the fan so it blows air toward the read exhaust fan; not toward the front of the case. Make sure you have wires, cables, etc tied up so you get good airflow through the case. If the inside looks like a rat nest, then you have one reason for running slightly warm.

    Really I would not sweat your temps; they are well within limits.

    well i dont know what the room and ambient temperatures are so that would help in seeing if its hot or relatively cool in comparison to it.... anything else i could try or do to decrease them more? and may i ask what are the current temperatures where you live now or your room temp

    I really would not worry about it too much. I am upstairs in my office so it is a little warmer than the downstairs of my house; probably 68-70F up here. The case sits inside my desk so it does run a little warmer than if it were not in a cabinet [I did install an exhaust fan in my desk for when it gets hot in the summer]

    About the only things I could possibly suggest would be to make sure the surface of the hsf is flat. Some are off a little. Take the hsf and give it a good cleaning with 99 or 91% alcohol. Now place a piece of fine sandpaper on a known flat surface ie glass or something like that. Move the hsf back and forth and check the pattern on the bottom. It should be clean all the way across. If it is just clean on one side, you know it is a little off. Sand/lap it until you get a uniform pattern on the bottom. Clean again to remove any sand and reinstall with arctic silver. Use ONLY a small amount ie size of a BB. Using too much will cause it to run warmer.

    Other than that, no suggestions.
