This. This is why I consider this mod safe to do on my machines, I had exactly the same thought.

Thanks for the great instructions vireland! I just did the mod on two games with the same fan you linked in your original post. Couldn't be more easy with all the info you provided. In particular thanks for the recommendation for the screws for the new fan - #10 x 1/2" self-drilling worked perfect. After shrink-tubing the splice for the new fan with the old connector, the only "tell" is the white goop between the inductor and board inside the power supply - unfortunately the fan wiring runs underneath the goop, so you have to remove/cut a bit of it to get the old fan out.

The result for me is I can still hear the fans if they are on, but just barely. They are NOT audible while playing which is fantastic! They also don't stay on any longer than with the OEM fans, which tells me there is plenty of air movement even with the lower CFM.

Small correction on the nuts needing to be removed (which are 11/32") - only two need to be removed from the bottom line connector cover, and none of the ones for the power supply itself need to actually be removed, just loosened as the two top ones fit easily through the larger lower hole on the bracket . Here's a photo showing what I mean.

My biggest objection to this version of the mod isn’t the looks - it’s that you have no idea what the temperatures are doing inside the power supply. Having the fan wired in as the original is critical as hearing (barely!) the fan come on *then off* is what confirms you are in the safe range. With your mod the temps could be climbing and climbing and you wouldn’t know it. Unlikely, granted, but it’s what doesn’t sit right with me.

That's what I was assuming (why have the tape over the slot where the original fan was otherwise?) but now that you mention it it's totally possible the larger fan is just running air through the old fan. That would certainly alleviate my concern above.

I was referring to D-Gottlieb’s version of the mod in which the internal fan is disconnected altogether. Obviously I wouldn’t have done your version of the mod on two of my games if I thought it was a bad idea.

It only comes on every so often - more if the room is hot, less if it's cool. Can't speak to Deadpool but my Iron Maiden that's only a few months still had the loud fan and I'd be really surprised if things had changed since then, but you never know.
