|
|
The fans in my 135LC are driving me crazy. So I'm thinking of swapping them all out for something quiet like the Noctua's

Has anyone done similar and had good results? What do you do about the yellow wires that monitor fan speeds?
And lastly, has anyone reworked the microscopic 60mm fan that blows through the heatsink on the deflection board? That one alone creates half of the mid and high frequency noise.

Fit a 3W 100ohm resistor in the red wire to the deflection board screamer.
Leave the other fans alone, at least in my experience. Making it run cooler will make it take ages to warm up, and poor fans will kill it.

Changing the fans would hopefully just make it quieter, not cooler. The fans in the XG are small fin with shallow angle and high rpm. Newer fan design has fewer but steeper fins at lower rpm.
I've tried slowing the small fan and then the def heatsink gets too hot and the image squishes in from the left and goes out of convergence.
I don't use any of the plastic case so I have more room to mod the deflection board fan. A silent 120mm fan with a reducer might do the trick.

The case is part of the cooling 'flow' that directs the warm air to the rear but keeps the drive cavity temp maintained. The XG deflection heat sync runs cooler then the PG series by nature if your not pushing it real hard in other areas. What ever you decide to do think stability and even drive temps. Doug
