Hello

Have my HTPC in a cabinet with a fairly standard 3cm clearence on each side, 2cm to the top and 5cm at the rear. Silverstone case, has 2x 80mm fans and a 120 on the psu, all rear exhaust.

Has anyone had the hot air exhaust to the front? The SilverStone LC20B has 2x92mm front slots, would these provide enough air flow?

As the cabinet is close to the wall, not sure if a pair of 12cm fans in the rear of the cabinet would help but its cheaper than a new case.

Any thoughts appreciated

Cheers

Steve

I would advise that you try the case in the cabinet as is and see what the temps are like. My GD01 has the same setup except an extra side vent for the CPU. I have 2x92mm fans in the front sucking air into the case but am getting tempted to remore them and leave then out altogether.

Temps are all fine summer or winter with no cabinet venting from side or rear at all.

Steve,

The two 92mm fan slots at the front are there to increase air input from the front of the case. This helps increase the airflow front-to-back, especially when there are a bunch of drives in the case.

The fan slots aren't meant to reverse the airflow and vent it out the front. Trying that is only going to cause worse temperatures in the case.

Do you actually have a problem with it overheating? If not, I'd leave it as is.

If there is a heat problem, and you've got the PSU and 2x80mm fans running, I'd look at your CPU cooler and VGA card cooler first, then possibly a 92mm fan at the front to put more air into the case.

Cheers
Buzzy

Confirms what i thought :)

A closer look at the front slots puts them before the hard drive bay (in some cases)

Even stress testing the CPU, it only gets to 42 so no issues there.

Thanks for that

Cheers

Steve
