Hi bubbleboy76,

Glad it worked out satisfactory. It's a big difference and I have not had any problem with mine. Even the CTS 8200 can be silenced by using 3x60mm and one 80mm fan.

The older 4200 (not "a") runs...

Brilliant.

I always use Papst for heavy duty and Noctua othervise. The fan's in the CTS 4200 and CTS600 är 12v so there Noctua works fine.

Hi johnwholst,

In the CTS4200 and CTS8200 and I think the CTS600 (don't remember, can check tomorrow) there are 12V fans. I do not have a CTS2000. Check for Papst brand fan's, they are the best in...

Hi,
