Note: This blower style cooler requires destruction of the GPU's fans' blades. I recommend buying an OEM replacement fan pair and preserve the original fans/shroud for resell/warranty purposes.
While blower style GPUs exist, my niche use-case required airflow to be exhausted out the top of the GPU as it is intended to be flat-mounted at the front of my RM23-502-MINI chassis using my custom GPU mount. While I could have used existing 4pin blow fans with adapters to achieve a similar result the noise and thermal performance wasn't as sufficient in my initial tests (plus the bulk of extra cabling was a challenge).
Extra Materials: NB: all bolts/screw are countersunk.
- 6x M3 x 2mm for mounting the fans to the fan mount bracket (A)
- 6x M3 x 4mm for mounting the lower case shroud to the fan bracket (B)
- 3x M3 x 8mm (up to 10mm) for bolting all three major components together (C)
- 3x M4 x 4mm for mounting the top case to the lower case shroud (D)
- 3x original tab screws for mounting everything back onto the GPU heat sink (E) (the 4th is a PITA to put in and out so I just keep it mounted with the 3 easily accessible tabs)
While there might be nicer ways to remove the magnet/rotor out of the existing fans I opted to snip the blades off and attach the blower blade component on top with friction-fit tabs; it's why I heavily recommend getting a spare set of fans first and mutilate them instead.
NB: Thermal testing done with furmark - numbers/graphs to be provided.
