N68c-s

Re: N68c-s

Apparently the southbridge heatsink runs hot.
Check out MCP too hot! Help.
From the first post in the thread:

Hello friends. I have the current specs from my sig.
I had a 9600GT before and i purchased a few days ago a GTS 450 gpu to replace my older card. I installed my new graphics card into the PCi-Ex slot then i reinstalled windows 7 x64..after that the drivers etc. standard procedure.
When i had my 9600gt and my old windows 7 x64 the MCP stood at 51-54C, now it's dead still at 65C and 67-70C if i play games or use CAD software. The radiator is so hot i can't even hold my hand on it for more than a seccond. The room temperature is always the same, the case is always open, the video card doesn't generate heat, the CPU is runing cold (maxim 38C in full load)
Can you, please, explain to me what is rising my MCP temp ?

Re: N68c-s

Let us know if you add a cooling fan to help lower temperatures and how much it helps. This will help others who are looking to lower temperatures. You might want to perform a quick test where you remove the computer case side cover and place a desk fan next to the case to blow air directly into your case. A 10 inch (250mm) or somewhat smaller fan on low or medium speed will definitely help.

Re: N68c-s

I'll buy a 80mm or 90mm fan, and install on the side of the case, and after the test reports the results.
PS: I want to buy this week.

Re: N68c-s

A 90mm or 92mm fan will usually be quieter and spin slower than most 80mm fans and usually will provide more air flow. For about $10 (USD) you can buy an excellent Arctic Cooling PWM fan; 80mm, 92mm or 120mm. I bought the Arctic F 92mm fan for my system. It has a fluid dynamic bearing (FDB) for longer life and quieter operation. The 4-pin fan connector should easily connect to an available 3-pin fan header on your motherboard. The fan prices on their web page do NOT include shipping charges from Asia.

The attached picture is from page 11 in your motherboard user manual and shows that the Nvidia Geforce 7025 integrated graphics are part of the nForce 630a chipset.
Good luck with your cooling fan setup

Re: N68c-s

One final random thought after profJims post. My old 9850 setup used the same chipset for a while but on a gigabyte mainboard. Mine (the BIOS) only had the option to pick what GFX was preffered, PCI or onboard, not to turn the onboard off.
I never had that heat problem, but I also used an ATI HD GFX card in it and not a Nvidia.
So now my thought, since you run a Nvidia card and have the drivers for those installed, Windows suddenly knows what to do with the onboard GFX part and that might be why it's running so hot.

Maybe your ASrock board BIOS' is better then mine was and will allow you to turn of the onboard GFX completely and thereby fix your problem. Maybe you also got a ATI HD4750 or similar GFX card around you could try for a test.

But if the extra fan works good (and it should), it is ofcourse the easiest and cheapest solution if something has to be changed.

Re: N68c-s

Thanks for the update.
Let us know if you install a larger fan and how well it works.
Ugly English? Nope, your post is easy to understand ;)

Re: N68c-s

I'll buy a good fan of 92mm and install along with the tube, leaving approximately 2 cm away from the chipset, I'll post the answer here, please do not close the topic.

profJim thank you for your attention.

Re: N68c-s

Glad to help out and that you are making progress with cooler temperatures.

Re: N68c-s

From page 18 of the ASRock N68C-S motherboard user manual:

2.5 Easy Multi Monitor Feature
This motherboard supports Multi Monitor upgrade. With the internal onboard VGA and the external add-on PCI Express VGA card, you can easily enjoy the benefits of Multi Monitor feature. Please refer to the following steps to set up a multi monitor environment:

1. to enable the function of onboard VGA/D-sub. Please make sure that the value you select is less than the total capability of the system memory. If you do not adjust the BIOS setup,
2. Install the onboard VGA driver to your system. If you have installed the onboard VGA driver already, there is no need to install it again.

Step 5 deals with winXP and win7 setup for a multi-monitor display.

Re: N68c-s

Hello again. I performed more tests in a new way.

Information test passed (fan + tube) on the side of the case.

I gave up that way because it generated too much noise.

Information of the new test:

The new test was performed with the same fan (that bad) I decided to remove the fan from the side, and puts it closer to the chipset.

Below the pictures of the test:
Link to the album: ImageShack Album - 12 images

notes:

After this test, I decided that this is the best that was in my hands, I did not want to shake the chipset.
And a very good thing, was that the fan was extremely attached(fixed, arrasted,I'm sorry but this verb is very hard.) hehe.

Test results:
Test time: 10 minutes


PS:I will still buy a better cooler and 90mm +, so I will post more results.

Re: N68c-s

What is the gray part that is on top of the chipset heatsink?
It looks like this part will trap heat from the heatsink and will interfere with cooling air from your new fan.
Can the gray part be easily removed?
You will probably need to hold the gold colored heatsink securely with one hand while you carefully remove the gray part.
You might be better off if you leave the gray part where it is while you first test with your new fan.

edit: Looking at the motherboard picture in post #12, the gray part is not blocking any cooling fins on the heatsink. Removing the gray part probably will not be needed for optimal cooling with your new cooling fan.

Re: N68c-s

The gray part, an invention is horrible, I put thermal paste (TIM) in the sink.
Should I remove it or leave anyway? (It's the thermal paste that comes with the Cooler Master Hyper TX3)

Re: N68c-s

It is hard to say if the gray part is helping or hurting with chipset cooling. This part might make the chipset hotter by trapping heat. If this part comes loose, it might cause a short circuit. With an extra cooling fan for the heatsink, I think that you will have better overall cooling with your "horrible invention" removed. The best heatsink cooling is where there is a lot of surface area to remove heat. The solid gray part might be causing slightly higher chipset temperatures. With your new cooling fan installed, it will also cool the motherboard area near the chipset.
