    I just installed a geforce 7300 GS video card. I decide to check my computer temperature, which I never did before I installed it. Speedfan shows:
    GPU 60c
    temp1 50c
    temp2 -128c
    temp3 40c
    temp1 47c
    core 40c

    PSU 300W

    Will getting a 500w PSU lower the GPU tempature? is 60c alright? the 60c is also constant, or higher but never over 70 unless I play games.


    This is a store bought PC. All I have done is installed a new graphics card.

    Hello Light and welcome back to the forum.

    Firstly I have marked your thread as "Open" in readyness for the team and members to help you with your questions.

    Yes you do appear to need a larger power supply.

    JB.

    My graphics card was pulling around the same temp 63 celsius yesterday, after converting a mpeg2 file to xvid. It usually reads in the mid 50 mark after the load is removed.

    As long as your temps drop down after a period of time you will be ok.

    Make sure there is no build up of dust and fluff on the fan as well. Use a can of compressed air and a natural fibre brush to clean the gpu fan...

    Alright thanks. There is no more room to add a case fan, unless I make some holes. I'll try getting a 500w psu.

    Video cards/GPUs run hot. The 8 series from nVidia can go up to 100C+

    It's perfectly normal. A bigger PSU won't lower temperatures, all it does is provide power. On the contrary, a bigger PSU will likely create more heat as it provides more power.

    I would take a look at this link eXtreme Power Supply Calculator Lite v2.5

    It will help you calculate what you need for power requirements.

    Although if the power requirements are not enough it will try to draw the power which can cause the PSU to get hotter adding to the over all system heat which means the GPU isn't in a cool environment.

    His current power draw is somewhere between 250-300W. The card he uses is a 7300GS which is fairly low power card.

    Whether you're overdrawing the PSU or not, it exhausts it's air outside the case, thus having little to no impact on ambient temperature and if anything, you'd only see a 1C difference which has no impact what-so-ever as that can easily be changed by the outside environment temperature.

    So while upgrading the PSU certainly won't harm anything, it's not going to impact anything except room for more peripherals to be hooked up or swapped out for higher performing ones.

    Either way, GPUs are meant to operate in hot temperatures due to their nature of running hot, so the point is moot and the overall answer is that it's perfectly normal and you should really only upgrade the PSU if you wish to add more to your computer.

    Sorry Darklord but I disagree with that perspective since it isn't good practice to run an item at its maximum rating just because you can.

    I'd venture that graphics card manufacturers would see quite a spike in sales if everyone viewed 100C as acceptable.

    For example my CPU in theory should be fine up to almost 100C as well but I wouldn't dream of running it even near there if I have any expectation of it to last.

    Certainly GPU's are designed to put up with a bit more punishment but in this thread we are talking about a 7300GT of which I happen to have one in one of my boxes and under normal conditions it runs at 45C.

    At the same time in this computer that I'm on I use a 9800GTX+ and it's running at 44C.

    Consequently unless there's some ridiculous difference in ambient room temperature 60C indicates unusually high temps for a 7300GT.

    Sure it will run but the signs are there that something needs attention.


    ETA: Another point that hasn't been mentioned is since we don't know what PSU is in the current box given that it's a low power one it likely has a puny fan in it too whereas upgrading to a newer one, in particular one that has the 120mm fan on the bottom might well help to exhaust more warm air from the case as well since there seem to be fan mounting limitations.

    Had a post written, but I hit back

    I'll muster up the energy to re-write it in a bit
