    CPU Overheating and shutting the system down

    Right so heres the story:

    About a month ago my PSU died (blown fuse I believe) so I bought a new one (slightly higher wattage).

    3 weeks ago I went on holiday for Florida for a fortnight, I returned to find that my mammoth CPU fan had broken the struts on the motherboard and fallen off.

    I managed to fix the CPU fan back on with another fan holder attached to the mobo BUT I did not have any silicon paste..

    Now my system runs fine unless I play games. Using Everest I have been monitoring my system's CPU temp which runs at 47 when idle and upto 85 when playing a game before it shuts down.

    My question is:

    Do you think I need a new CPU fan or just some silicon paste?

    The idle temp seems ok but it really shoots up when I run the games..

    Im running a AMD Athalon X2 4200+ and I dont have any other cooling fans ... think I need some?

    just the thermal paste should do it if fan still works (scrape off existing paste first)

    You need paste between the heatsink and the chip. If that was ok then it's just the fan.

    IMO I would replace the fan as they are not that much and would be a put my mind at rest.

    The best thing for you to do us buy some thermal paste and a heat sink for you cpu which is designed to help cool cpus that are overclocked. I have a 2.4 ghz quad core overclocked to 3.2 ghz ande cpu temp is 34C. with a heatsink which is recommened for overclocking

    Definitely get your hands on some new thermal paste and (as others have said) clean off the old stuff before applying it. In addition I would take the opportunity to clean any dust that has gathered on the fins of the heatsink (if there is any visible) as that will improve the rate at which the air from teh fan removes the excess heat from the heatsink fins.

    I have some thermal paste left over from my recent build

    £1 and i can post tomorrow?

    I heard submerging your entire baseunit (and ideally your montior too, if at all possible) in a large container of water helps maintain optimal CPU operating temperature ?

    This is true. However, it only works if you use distilled water (the impurities in normal water are what conduct electricity), and are a fish.

    'and are a fish.'



    hahahahahahahaha :-D

    Clear off the old thermal paste, and buy yourself a Freezer 64 Pro.

    If it will fit in your case/onto your mobo.

    Funny you should say that ... thats exactly what I have - a Freezer 64 Pro!

    Cheers guys - ordered some paste will sort it out when it arrives ;-)

    Nice one

    Just make sure the Heatsink is installed right and actually flush with the CPU :thumbsup:

    I just saw that as I was ordering ... about £33 on ebuyer..

    Problem is - I cant be assed to remove the mobo incase it needs a plate installed..

    Besides I think the Freezer works fine atm (I think!)

    Yeh i saw the reviews.. this plate thing sounds weird but I'm determined to do it

    9700 + Intel E7200 = WIN

    good luck :-)

    ok so I ordered plenty of thermal paste, applied it and hey presto things seemed to be better..

    Championship manager would now run without crashing, but...

    International cricket captain was still rocketing the cpu temp and killing the system.

    As such I decided to stop taking risks of frying my cpu and removed the fan:

    It appears the issue was the Freezer 64 fan. Im not sure how or why but it seems to no longer increase RPM when the cpu temperature rises.

    I know this because I took a stock fan from my old skt939 3200+ single core and stuck it on.

    Now it does sound like an aeroplane about to take off and does reach speeds of about 6000rpm BUT it still keeps the cpu temp below 60 degrees...

    Question is - can I fix the Freezer 64 or will I need to buy a new fan ... If I do I may go for a Zalman - although I really cant be bothered to remove the mobo to change the holding plate for the fan struts (i think Id have to I cant remember)

    But im put off by the freezer now so I wouldnt buy another one of them (Always thought it was louder than my dads zalman anyway)

    Any thoughts?
