ram memory cooler for 80mm fan

thingiverse

This is a RAM cooler that uses a standard 80mm fan instead of the usual pair of 40mm fans. The commercial coolers I've used have usually had two problems: - they had low-quality 40mm fans that started failing in well under a year. and, - they didn't fit the memory very well -- they had a weak grip on the memory and could easily be dislodged when moving the machine, and some CPU coolers had hoses that prevented the memory cooler from attaching correctly This uses a single 80mm fan to do the job. Even the low-end fans should last several years before they start to get noisy, and there are lots of options if you want something specific. Downsides: it's bigger and won't fit all cases. If you have 5.25" drive bays near your memory, you'll have a hard time getting this to work. ### Notes For my memory cooler, I've offset the fan so it's not centered directly over the memory, which gets it out of the way of the AIO cooler's hoses. If you don't have that problem, there's no reason to have that weird offset. With extreme offsets like mine, it's difficult to get a screwdriver over the holes to screw in two of the fan's screws; you might need to switch to using a nut & bolt instead. This print clamps onto the memory socket, and the grooves in this print may not line up with other brand sockets. If your socket looks considerably different from mine, you may want to print just the bit that fits around your memory and do a test fit before committing to the whole (for me, 10 hour) print. If you print it in the obvious orientation (fan-side down), the springy bits that clamp onto the memory socket will be in the weakest orientation. That's how I print it, and I haven't had one break on me, but it does worry me. [edit: actually, I've had a few failures now, but those were with either ~5 year old PLA that had seen some humidity and some new silk PLA which has absolutely horrible layer adhesion] I did have plans to improve this by adding some vent holes on the ends, and possibly some vertical channels down the sides to draw air around the outside of the memory. But it's actually working very well without those mods, so I'm going to leave well enough alone for now. ### Libraries This design uses the wonderful Belfry OpenScad Library for its "skin" function. The required files have been inlined into the `memoryfan.scad` file to make it work with the customizer. If you want to make non-trivial modifications to this, I've included the un-inlined verision of the source in memoryfan.scad.txt (renamed to avoid confusing the customizer).
