Case fans setup

[deaddew]

I am not sure how should I place my fans for best cooling. https://imgur.com/a/VtZzY

The case is a Thermaltake Commander MS-III. All fans are 120mm, the top one is from the Corsair H45. 

My GPU temps are getting quite high.

3, especially if the GPU temps are high, just dump some fresh air right onto it

I don't know if it's relevant, but I forgot to draw the PSU fan which is right under the GPU and sucks air

If the case has an intake underneath the PSU mounting position then it doesn't affect anything else, since it doesn't share the air with anything else.

 

As for the configuration of case fans: 3 should be enough for most systems, but you would want 2 fans in and one out to maintain positive air pressure inside the case compared to the outside air, otherwise more dust will seep in from small openings into the case and you'll either have to clean out the insides more often or if you don't your cooling capacity might be impaired by the dust gathered inside the system.

 

I would suggest putting an intake on the bottom and on the front, and then just one fan blowing air out of the back of the case.

 

This TQ video explains the positive airflow well.

PSU sucks air anyway. It better if it can suck it from outside the case so it doesn't fight with GPU. How high are GPU temps? Something like 70-80C is still fine for load. Also which GPU it is?

 

Have one fan as front intake and one as rear exhaust. 3rds placement is to either bottom or side as intake, depending on which GPU cooler style it is.

It's a Gigabyte Windforce GTX 1060 6GB, it was climbing up to 80-82 degrees in some games and it idles at 57 degrees which I guess it's fine for now, but I don't want to think how hot it could get in the summer lol

Ok, thats pretty hot. Add fan to bottom spot and front. The card has open-style cooler, so side panel fan isn't doing much either way. If you want to try with side fan, have it exhaust.

Use all the damn fan slots. 3 intake, 3 exhaust, just like the picture.

Right now I have it like in picture 1 in my album and I'm planning to get more fans, but I've ran out of slots in my motherboard. Do i need some special molex adapter to connect them directly to my PSU?

You can either:

• Get a splitter, something along those lines. Just make sure to check if the motherboard has 3 or 4 pin connectors and do the same with the fans you have and the ones you're going to buy

• A Molex to fan header connector

 

I'll honestly go for the first option. In case of pwm fans (4 pin) you can directly control their speed through softwares like Speedfan.
