Newly installed graphics card heating up CPU

I bought a decent cheap PC that I planned to use to run high-end games once I had made a few modifications. I replaced the PSU (The original only putting out 350 measly Watts) and I replaced the mediocre integrated graphics card. Ever since I replaced the graphics card, however, my computer sounds like a damn jet engine whenever i'm running games, even Garry's mod. I downloaded a few temperature monitoring programs, but they say its around 90C on idle, which is total crap. In BIOS, it says its around 58-60C, and thats while not doing anything special. I figured it was the graphics card fan at first making the noise, but now my CPU seems more likely. Would upgrading the CPU fan help with this problem?

Specs:

AMD A-10 Quad-Core 3.7 GHz
8 Gigabytes DDR3 RAM
Nvidia GeForce GTX 650

OK If you can give us the make and the model of the GPU it will help. BUT if it is one styled to vent the heat into the case It is possible for it to heat up the CPU a little.

Will a new CPU cooler help? Well yes it will BUT there is one thing you should find out first. This is why your CPU is getting so hot or why the fan is spinning so fast. Check and make sure in the Bios you still have Cool and Quite enabled. This controls the CPU core speed and fan speed. Also you may want to try to reseat the CPU cooler. This will require the replacement of the thermal paste. You may have bumped the cooler enough, while you were in there, to break the good contact it had.

The SATA cables on the PSU were very difficult to put into my CD drive and hard drive due to the centimeter and a half difference in size between it and the previous PSU. I definitely bumped a few things around, but I was trying to be as careful as possible, and always grounded myself.I dont ever recall even hitting the fan, although there is a lot of wires that are being pushed against the fan. I did a little research into others having the problem, and one person suggested that the graphics card's capability can sometimes outrun the CPU's and cause the CPU to constantly try to catch up to the grahpics card. Which would make a lot of since in my case. Also, i'm not the most experienced person in terms of computers. I had a buddy mostly walk me through replacing a lot of the components. I'm not familiar with thermal paste or the make-up of a CPU fan. Also, I already tried modifying a lot of settings in BIOS, including enabling cool and quiet. It didn't make a single bit of difference. I've already sunk in roughly 800 dollars into this PC. I'd prefer trying to solve the problem without having to upgrade the fan.

Be sure you have plenty of ventilation in the case. Any extra wires try to tuck between the motherboard mounting plate and the rear case panel. This allows for air to flow freely through the case. Be sure to have at least an exhaust fan on the back of the case. It is best to have intake and exhaust fans.

If you have wires around the CPU cooler the cooler can not work properly. The hot air is getting trapped around the cooler and causing it to heat up.

EDIT: example of clean wiring. tuck as much as you can between the motherboard mounting plate and rear case panel.

This is an image very similar to how the wires are currently set up in my PC. I mostly shoved the unneeded SATA cables and such behind the CD drive located next to the PSU. The graphics card in the pictures is a real piece of junk, it was one of the few I bought to test out, my current one is much bigger, but not blocking anything and the fan is facing the same direction as the one in the picture, towards the bottom of the case. I apologize for the lacking of quality. Its all I had without opening up the thing again. The noise of this problem is really annoying, but the CPU being hotter than normal wouldn't cause any permanent problems would it?

Are you sure you are reading the temp monitors correctly? the New AMD's are really funky to read. 1 temp is the socket temp and the other is the temp that is left till it throttles.

If your wiring is like this pic then this is not an issue. It looks like that case uses the PSU to vent the hot and not a fan. If there is a spot on the back for a fan I suggest putting one in.

Yes adding a bigger GPU can make the CPU work harder but hot heat it up to 90°C. be sure you are reading the monitor in °C and not °F.

It is possible while connecting the sata cables to HDD you bumped the cooler. Thermal paste runs about 8-15 USD and you should have some on hand anyways for when it dries out under the cooler. If you are reading the monitor correctly then I suggest you try to reseat the cooler.

Thats the new PSU i recently added to the PC. The previous one did not have a fan on it like that. I trust the BIOS's 58C-60C much more than I trust those temperature monitoring programs on the AMD processor. Some of the programs I tried flat out weren't compatible with my CPU. My fan would be exploding from overworking itself in games if the idle temp was 90C. It was in Celsius, I know that for a fact. Ill look into thermal paste and/or a more powerful CPU fan. I thought I would be able to create a monster for cheap, but I guess I overestimated pre-built PC's cooling and electrical output abilities. Thanks for the help!

Oh. I didn't know there was a difference. Ill look around and see if I can figure out a solution with thermal paste. If all else, ill just leave it how it is. The CPU may blow out in a few years, but that's pretty much when it would become obsolete anyways, and I could just use the rest of the parts for a new build. Thanks!
