Unfortunately I have to work this weekend switching from the multi-migrated W2K -> W2K3 -> W2K8R2 domain to a new, pristine W2K19 domain😏. (I know I’m a little late)
Fortunately this gives me plenty of time tinkering with retro stuff instead of watching endless progress bars😀.
As mentioned before I had some problems with my Voodoo5 5500. One of the original fans is just too loud/noisy. I tried using silicone grease and sewing machine oil to no avail.
During the disassembly of the fans I noticed the noisy fan had a missing sealing rubber. As the original stickers were untouched I have to assume it was missing from the beginning.
Now, if I have to replace the fans I might as well do it properly.
I removed the original fans, the factory coolers, put on some Arctic Silver and fit some one inch copper coolers on top of the BGAs. The new fans have a voltage range of 7.5-13.8 VDC so I’ll solder in 47Ω resistors to have them run as slowly as possible while keeping them in spec.
Finally some aligned coolers on a Voodoo5 5500...
