    Angry CPU fans speeds up then shuts PC OFF

    I am in need of some serious help as I not only have a serious issue that restricts me from using my computer but I would also love to learn how to solve this issue at hand. Please read everything.

    I recently bought my brand new Asus desktop computer last year...
    ASUS DESKTOP PC AMD FX-Series, FX-4150 (3.8GHz) 8GB DDR3 1TB HDD Capacity Windows 7 Home Premium 64-bit.

    Now, as of before-yesterday I purchased RAM + Graphics card to update and to play games on my computer with smoother performance.

    RAM = 1 x G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-

    http://www.newegg.com/Product/Produc...82E16820231428

    Graphics Card = 1 x ASUS Radeon HD 6450 EAH6450 Silent/DI/1GD3(LP) 1GB 64-Bit DDR3 PCI Express 2.1 x16 HDCP Ready Low Profile Ready ...

    http://www.newegg.com/Product/Produc...9SIA1N82KK1704

    Long Story Short: Before putting on my new computer parts I took out my fan, the silver thing under it, and even the processor. I cleaned the ENTIRE fan and motherboard so there is little to no dust, then...

    I put on these new parts on my computer and as I turned on my Asus desktop it turned on normal but 5 seconds later the FAN sped up 10x faster than normal and in less than 30 seconds the entire computer shuts down.

    After I bought and installed my new RAM + GPU my computer will not run. The fan speeds up 10x faster than normal, makes a loud sound then the entire computer shuts down automatically.


    Have I done something wrong? What must I do? PLEASE HELP ME!
    (I have enabled email notification in case anyone posts any further questions I will answer immediately!)

    Your description sounds like it may be overheating.
    Are you certain you properly applied heat sink compound when repositioning the cooler on the CPU?

    It sounds to me like you need to go back in and recheck and reseat your CPU cooler to the processor.
    We hope you didn't reseat the processor improperly, that would be a fantastically expensive mistake for which there will
    likely be no coverage for.

    Another thing...

    You should NEVER have done all that work at once, now you [theoretically] face the challenge of
    troubleshooting the newer components you just added too.

    CPU fans have a small blob of thermal conducting compound on the surface that sits on the CPU. If you cleaned that off your CPU will overheat and shutdown.
    You can buy new thermal compound.

    I had no internet for a few days.

    My computer is up and running although my fan is SUPER LOUD and it doesn't stop running whenever I have a game up...

    It's incredibly loud but at least it works so now i'm stuck with another problem although this seems like a minor issue.

    New problem: MY FAN

    I may have re-seated it incorrectly but now I have fixed that (took it out again and put it in the right position).

    What suggestions do you have?


    edit: My processor can only be positioned in one way, so there is no way to make that mistake, although the silver metal part (CPU cooler) is what I had positioned incorrectly + my fan. The processor is fine, but the fan doesn't stop running and therefore the sound is EXTREMELY LOUD and obnoxious.

    Check the BIOS for CPU and motherboard temps and if they're good, see if there is a setting for speed stepping the fan depending on thermal stepping.

    Also, here's the weirdest thing of ALL...

    My games now have lag ever since I put in my new graphics card :|

    Like, how in the hell does that even happen. There is no logic in that. It doesn't even make sense.

    That happens when something is not right.
    You haven't sorted the temperatures out if the fan runs very fast. Install SpeedFan or other hardware monitor and check the temperature - it should be 70C or less.

    cheers, Paul

    I would suggest getting a new fan. This would be a quick, easy, and inexpensive solution to your noise problem.

    Your new GPU is a HD6450?

    Yes sir, that's what it says. Why are you asking?

    So now the question is, which fan should I buy that is under $100 from Newegg.

    We also have to figure out why my games aren't 100% lag free. I mean the GPU is 1GB so for a game like League of Legends or even WoW it should be fully smooth.

    Maybe you need an additional case fan to move more air through the case for the CPU/GPU fans to use. Do you have any case fans?

    cheers, Paul

    Your temps look a bit warm. I hope that's not at idle.
    But yes, a properly ventilated case with enough fans to move the air out is a must.
    Otherwise you may end up with fans running at max. capacity and still not doing the job.
