Technically yes but there where no warranty void stickers on mine  ^-^ So just store the original screws if you replace them with rubber fan mounts.

Yep, just keep original fan and screws, to put them back if need arises. If your hands are straight, there is nothing to worry about. If I do something like this, I also wear ESD gloves to avoid leaving any fingerprints inside  :-DD.
Fungus:
Anybody here feel up to doing the new "Wolf" test?

Apply a square wave to an input, display "rise time" on screen, then zoom in and out.

The idea is to see if the rise time is computed with screen pixels or with sampled data.

If the displayed rise time varies then it's using screen data.  :popcorn:

MrWolf:
"Wolfs test" thread is here:

It should be interesting since GW Instek seems to have excellent engineering team. Just bit lacking on marketing side  :'(
NorthGuy:
May I ask you if 10Mpts setting is per channel or overall. E.g. if you sample 4 channels, do you get 10Mpts for each (40Mpts total) or is the overall amount spread around channels (e.g. you get 5Mpts or even 2.5Mpts when you have all 4 channels on).
