Motherboard Running Hot With New Graphics Card

[Sapper13]

So a while ago I got a new GPU after using the CPU graphics, just because I never use to game/ Or play games with high quality graphics.

So anyway, I noticed my Motherboard was running hotter then usual, maybe 10 degrees more, and the CPU was a little hotter too.

Then today my Nvidia GT 730 turned up. Started my PC and checked my temps. They are at least 20 degrees hotter now. My CPU is around 61 and my motherboard is 75 degrees after loading Battlefield 4 but not playing it and then let sit for a while, and they don't go down.

Motherboard reaches 85 degrees and the CPU reaches around 75. I can't play Battlefield because the FPS drops from 50 down to 17 and sort of freezes, then goes back up again. Is it to with the heat or what?

I also have a desk fan blowing into my PC to keep it cool, and they still reach them temps.

Windows 7 Ultimate 64-bit SP1
CPU
AMD Athlon II X2 245
Regor 45nm Technology
RAM
4.00GB Dual-Channel DDR3 @ 533MHz (7-7-7-20)
Motherboard
MSI 740GM-P25 (MS-7623) (CPU1)
Graphics
DELL E1910 (1440x900@60Hz)
2047MB NVIDIA GeForce GT 730 (Gigabyte)

Im going to upgrade my CPU and Motherboard soon, do you think thats the issue?

Thank you

It won't be long before you no longer have an operational computer. I'm guessing that you put the system together yourself and know about using the correct amount of heat paste. With a PC running demanding software like games the choice of case and cooling fans is a number one concern. Even running the desktop with the side off and a fan running isn't working so go back to basics and replace the case.

Yeah okay. So you think its as simple as the case? Thanks for the reply

Well I like small and compact but when I see gaming desktops in a computer shop window they are typically huge with a multitude of fans. A high power computer is going to generate lots of heat.

If it were mine, I would be very concerned. The temps are way too high. I would look for blockage in the ventilation, clogged fan in PSU, dust in the cpu cooler, air bubbles in the thermal paste between heat sink and cpu, wiring bunched and blocking air flow, etc.

Get the dust bunnies out.

Add a case fan as well (120mm are nicely quiet) - the GPU adds 55 watts of heat inside the case.

Target temp for cpu: 40C idle and 50C under load (>60C is high and >70-75C could kill it).

Northbridge at 75C is a bit toasty - but 85C is not good.

The 730 seems to have a higher max temp, but with all things computer, cooler is cool.

Yes very true, it is also Summer here, and it gets pretty hot in my room, so I'm also thinking its to do with that

Haha yeah its a little worrying. Cooler day today then yesterday and I'm getter cooler temps. CPU is around 40 degrees and motherboard is 55. Its still a bit hot, but also I had a lot of things running yesterday which would of caused the heat during gaming. When I'm done with a game, the temps go down quite quick.

The 730 never gets over 50 degrees haha

If ambient is 40C, then your system will run a bit hot - but "Motherboard reaches 85 degrees and the CPU reaches around 75." is too high and you risk real problems. Maybe you should move to the basement during the summer weather.

Yeah I think that's a good idea, as it runs a lot cooler today
