Why is my system so hot?

[andru]

Hey guys this is my first post here. My current system is in a Cosmos 1000 case. Right from the box, it had horrible cooling. So, I decided to get rid of the crappy stock fans and replace them with high CFM Yate Loons. These fans push a LOT of air. However, my temperatures do not seem to have improved one bit. What is going on here?

You should list out all your parts.

How are you getting these temps?

Post your Temps for:
CPU
GPU
Mainboard
HDD(s)

Bottom fan pulling air in.
PSU mounted horizontal fan up
Rear fan exaust
Top fans exaust
CPU HS fan air flow towards the rear exaust fan

Is there an inlet fan in the front of that case anywhere or a provision for one?
Is your HSF firmly mounted to the MB?

My current specs:

Intel Q6700
EVGA 780i
6 GB OCZ SLI Ready RAM
EVGA 9800 GT
WD 640Gig
Silencer 750w
Cosmos 1000
Zalman 9700NT

Temps:
CPU-45 CIdle (was 28 idle in my Antec 900)
MCP- 70 CIdle
GPU- 70C idle(with fan at 60%, anything higher is irritably loud)
HDD- Don't know, but I nearly burned my hand touching them.

Here is an outline of my current fan placement. The yellow things are the fans and the blue lines indicate which way they are pushing air.

no computer genius here but your top fans should probably blow out instead of having one blow in. You are basicly sucking the hot air your throwing out right back in the computer case. You Definatley need to get a fan in the front to blow on your harddrives.

Airflow in the case should idealy be going front to back, bottom to top, improving tidiness inside the case can help airflow

What the last two guys said is right. Maybe find a higher CFM fan for the bottom.

Is it sitting on a hard surface? Not blocked by carpet?

Hmmmmm,kind a hard to tell from here,but maybe a cooling solution for the graphics that exhausts out the back might help,plus the Zalman on the cpu dumps hot air everywhere inside any case,not a good idea,is most desirable to exhaust heat out back or up top..

I had the Cosmos 1000 for about a week. Was totally unimpressed with its airflow so I took it back to MicroCenter. Also, that Zalman 9700NT (which I've also had) is not going to give you great cooling on that quad.

Snacks for thought.

What a mess! Tops fans both need to blow out. Bottom fans need to be situated in at front of the case, blowing air across the drives, pulling in air directly from the outside.
