Hot GPU/Chipset for Zotac ITX 8200

post #1 of 8
Thread Starter 
So, I brough a mini-itx Zotac GF8200-C-E with the Sempron 1620-LE CPU and comes with the intergrated nVidia geForce 8200 chipset/GPU.

My biggest problem is how hot the chipset/gpu is. It's actually burning hot to the touch after leaving it on for 5-10minutes. I can't even put my finger on it for longer than half a second. What this leads to is a very hot case. I got an apex-008 with 2 fan, one inhale and one exhaust running at 900rpm for silent mode.

After running for 2 hours with a 2200rpm CPU fan on the processor, the PSU surface was burning hot, and the GPU/Chipset couldn't be touch, but the CPU heatsink was decent. And of course, the exhaust fan was producing very hot air. The temp inside the case was probably 55-60c at worst.

I'm asking if there's any way to underclock or undervolt the GPU/Chipset? There's a option in the bios screen to lower some setting for the GPU/Chipset but I've never really overclock before as well, so I didn't know much about overclocking or underclocking. And of course, I wanna underclock and undervolt my CPU as well so I could just purchase a quiet fan and run it at silent mode too.

Thanks.

Human skin starts to burn by direct contact* from as low as 45C. Electronic components can be safe over 100C. Just because something feels hot to the touch, doesn't mean it isn't within normal operating temperatures.

Maybe but i doubt the temp thats inside will be good for my hdd. Previous my hdd was around 45c with the intel atom which was at around 45c for the motheboard and it was just slight warm.

Now thoughr, its hot and i think the hdd will be in the 55c to 60c temp as result.

Yep, for HDD, this kind of temp >50C is bad. I didn't notice you mention drives in the original post.

Can you describe or show some pictures of how you have the fans?

Ya, it wasn't included in the original post. smile.gif I had to rewrote it because my first post was too long, so I left out some stuff.

Previous motherboard vs new motherboard temp inside the case is around 5-10c hotter for the new one. The fact that with my previous motherboard, my HDD was running 45c at max, I don't want to think what the new motherboard's HDD temp will be at.

If you google apex 008 pic, you'll see that there's vent hole on both side of the case. I have a 80mm inhale fan on the PCI slot side, and on the other one is the 120mm exhaust. I actually have it standing vertically, so the side vent for the inhale is pretty much half a inch from the ground (not on the ground because of the rubber foot) and the 120mm exhaust is on the top. They're running less than 1k rpm and anything higher will cause me to notice the noise when I sleep. So...there's not much chance that I can increase the RPM on the fan. Actually, the 80mm inhale is on the PCI side so it actualy blows through the both chipset/gpu and CPU heatsink and than exhaust on the 120mm.

At this moment, I'm drawling blank on what to do. I'll probably try to lower clock the CPU and try to do the same for the chipset/gpu and if that doesn't work and nothing improve, I'll probably just use my intel atom instead. That and the intel atom draws around 20watts less than the zotac at idle. smile.gif

Thanks for replying, WiSK

Huh, I manage to underclock it on the processor and GPU. The GPU is still hot but the processor is very easy to cool with a 1500rpm cpu fan. The amount of heat is noticeable less. But to do so, I had to change the GPU setting all the way to the minimal, and lower the core ratio to the lowest that I could get to it. Not sure if it's worth the effort for a bit less heat. Hmm. Gotta see what the temps are like for the HDD once I installed w7.

I was thinking the PSU might be causing a lot of the heat as well. It's not a very efficient model. Perhaps you can exchange it for something more modern?

might be. but I don't want to spent more than I needed. The amount of time that I've spent on this particular file server has been...well. Let's just say this is probably my 4-5th motherboard in the past few months. I'll just give it a quick install of windows and see how the HDD temps are, if it's too high than I'll switch back to my old intel atom and just leave it at that. This is way too much time consuming.

Thanks.
