How should my fan set up be? Push/Pull

[heartspains88]

My cooler master cosmos 1000 has the door mod for a fan there. It has a bottom mounted fan, two top mounted fans, and a back mounted fan. All of these are 120mm

I recently ordered a low profile 120mm since my noctua nh-d14 will not allow me to have a full sized door mounted fan.

The set up I plan to go is:

Bottom fan - Pull

Door fan - Pull

Both top fans - Push

Back fan - Push

Is this ideal for my setup?

Right now my temps are great, I'm overclocked at 4ghz on my processor and it never gets above 45c

However my video card is an absolute heater in my case (asus 6950 direct cu ii 2 gb)

Only reason I'm not 100% sure on this set up is that's only two fans bringing air in, and 3 fans pushing out. More out than in, not sure if this is ideal.

For other questions on set up it's all in my siggy.

low profile 120mm? Thats going on the door right?

The norm in PC cases is the Side, bottom and front fans are intake and the top and rear are exhaust.

Why, Well the front generally pushes air over the HDD's and onto the video cards, the side fan pushes air directly onto the video card.

The the rear and top fans are normally mounted next to the CPU fan and the CPU generates a lot of heat so it would make sense for those fans to exhaust the hot air directly out of your system.

But also this all depends of where the fans are located, your side fan might not line up with the video card so it might not be the best setup, I would set it up the default way then think about how well you thing the fan direction is onto the components. you also need to get a balance, no use having 3 fans intake and 1 fan exhaust. But that's common sense

Just experiment a little

see what works best.

yea tom. a full width fan pushes on the noctua and makes me a tad uncomfortable.

as well as my video card acting like a heater. as I said my temps aren't horrible. also I don't have an oc on the gpu. and the Asus 6950 I have is supposed to be a fridge.

@ygg thanks for the insight. that was the plan but I wanted to confirm.

Does the side fan make any difference to temps though?

Ive always favored windows tbh

 

[heartspains88]

to be completely honest tom. when I noticed the fan pushing on my noctua and pulled it out completely my temps improved a few degrees. so all that's there now is a screen.

however the size of the fan could contribute.

on a side note. if I don't use a fan there that would leave me with four fans total. one bottom. three top and back.

I'm not sure if my case has other fan mounts available. ill give a closer look tonight.

push = input

pull = output

i think you have got them the wrong way around

 

[heartspains88]

it seems your right. so flip flop them haha.

on a side note. from reading the specs. apparently it has a front hdd fan mount I'm not using.

**update** swapped all my fans as I had mentioned above. Mounted a fan on the hard drive bays blowing onto the gpu.

Still dont have the low profile fan for the door as it's in the mail.

However my temps have dropped 10-20c accross everything.

My biggest cause of heat was my gpu, and after 45 minutes in furmark it capped out at 57-58c ( was jumping between the two but never above ). Which since I've read the Asus 6950 Direct CU II 2GB can easily push 85c, those are great temps under complete load in furmark.

When before my gpu in furmark would climb, and climb, and climb.. once it got close to 75-80c I would always shut it off. Keep in mind these were furmark temps and not gaming load temps, however they are insanely better obviously.

My cpu likes to sit comfortably 40-45c under load. In prime95 torture test. Generally around the 40c mark under normal gaming/use load.

Very happy with my temps, and I assume as I make other changes here and there they will improve even more.
