CPU & GPU Temperatures too hot.

I'm pretty new to PC building, but I managed to build a PC back in June of this year and was pretty happy with it, at least initially. However, as of late, I've been having a series of problems with the PC, all of which revolve around temperature of my components, so I was hoping to get some advice on what I can do to help fix the issue.

CPU - AMD FX-8320 3.5GHz 8-Core
MoBo - Asus M5A78L-M/USB3 Micro ATX AM3+
RAM - G.Skill Ares Series 8GB (2 x 4GB) DDR3-1600
HDD - Seagate Barracuda 1TB 3.5" 7200RPM
GPU - PNY GeForce GTX 770 2GB
Case - Rosewill FBM-01 MicroATX Mini Tower

At first, my issue was with my graphics card, which would go up above 90 C during gaming (Watch Dogs). While the card should be able to handle 97 C in Theory, some friends have told me that one should preferably avoid going over 90 C, so I tweaked some settings in MSI Afterburner as a temporary measure, but am sure that there's an underlying problem that needs solving.

Now, the problem is my CPU, which is running in at over 60 C regularly when the PC is in anything but power saving mode, but even then it will overheat itself to over 60 C while I'm rendering videos. It's been getting worse as of late, till today it went all the way up to 75 C. I don't think the socket is supposed to handle that kind of a temperature without crashing. Throughout the situation, I looked at the temperature and voltage, noticing that it kept going up and down, like a result of the CPU throttling itself whenever it got above 70 C again.

I initially thought the primary problem was just the case since it is rather small and cheap for the kind of power the PC is packing, but now I'm, starting to suspect the PSU may be struggling to keep up with the power demands (500w just barely handles the kind of power PCPartpicker noted (444W). If I could I'd like to resolve this issue with as few purchases as possible, but if need be, I can spend up to $100, though I may be able to get a bit more or less is possible.

I'd prefer to expend all of my software/light maintenance options before resulting to putting my wallet on the line, but if need be, I suppose one must do what one can for one's livelihood.

All advice is very much appreciated.

  1. That rosewill case is never going to keep those components cool .

    The airflow is not going to be good with an 80 mm outlet fan

    Buy a corsair 350D
  2. Best answer
    get a atx case with a good air flow with at least 4 fans in so you will be able to cool down this system .
