  1. specs:
    amd 2500+ OC to 3200+
    mobo gigabyte 7s748
    cheap 450w power supply
    coolmaster fan (looks like a jet engine)
    cpu +5%
    confused look on my face
    Im new to overclocking
    Dont understand it:
    when i turn the fan speed knob the temp dosnt go down more than 1 degree or nuthin at all(celcius)

    do i need different thermal grease, or more or less (is there such a thing as too much?)

    idle is 50*C, im not worried about that but
    would appriciate any comments

    (not an invite to sarcasm..... maybe just a little)

    thanx guys

    Welcome to TechSpot forums

    Maybe the temperature doesn't drop much because the hot air stays inside the case. In other words, how's the airflow in & out the case?

    Yes exactly you probably need some better case fan.

    The exhaust ones are the coolest.

    by using a couple of h/d cable ties to hold the 660g fan/hs a bit better the temp has dropped to 42*C at idle

    i got this fan on brackets mounted on the fan, also it dosnt make any difference what angle the case is on

    the case fan is a bit poor so i will replace it and see how that goes. the case is usually open so

    here's a pic attached of what im going on about

    Temperature can easily change based on ambient temps as well. Keep in mind a cooler day will definitely equate to cooler temps.. Sometimes by even more than 10*

    im really starting to think that its not seated properly on the cpu

    42 is normal...........and, when u play games, boom, up to 59 or so.......up or down on the fan rpm and nada, normal, for me......motherboard monitor does a good job of visualizing a general range of cpu temp...but, it's seated properly, you can count on that......sure u can reduce the temp, ie: water cooling, but, what for? other than fan noise, which u don't have, so forget it. considering ur current oc, ur staying pretty cool.
