Introduction

Are you having trouble with keeping your RAM stable or just want to push a little more performance out of it?  A dedicated RAM cooler will help keep your system from crashing due to your RAM getting too hot and losing stability.

For many more cooler options and intake ducts to install on your fans, check out my DDR5 RAM Cooling Kit.

These coolers and intake ducts are 100% 3D-printable and only require that you provide one or more fans as well as some m4 bolts or TPU filament to attach them.  I recommend using some TPU filament to attach them as it adds less weight, there is zero risk of shorting out any electronics with it versus a metal bolt, and it is cheaper.  With this included kit, TPU filament or a cable tie is required for installation if using the provided directional intake part, as there is no room for a bolt head on it.

I printed most of my coolers and intake ducts out of CF PETG and CF ABS, which are strong, have suitable temperature resistance, and are quite stiff.  I recommend you also make yours out of ABS or PETG, or some other plastic that has good enough temperature resistance for this application.  I would advise against printing this out of PLA as the poor temperature resistance will eventually result in failure.  PETG should be able to survive up to about 65 Celsius with some load on it, so it should survive even in a poorly ventilated case.  However if you want the peace of mind, ABS, ASA, or another higher temperature plastic will work too.

Notable Printing Considerations

• This is a load bearing part subject to possibly high temperatures as well as the weight of one or more fans.  It is recommended to not overly skimp out on perimeters when printing this part, just to be on the safe side.  Three or more perimeters is recommended.

• It is recommended to print the parts out of CF PETG,  CF ABS, or some other material that has good enough temperature resistance for your case.

• If printing with a carbon fiber-filled filament, ensure layer heights do not go below 0.2mm and try to keep a 0.25mm+ layer height where you can to prevent clogged nozzles.

• Some of the coolers and intake ducts are quite large and may be subject to warping without a suitable enclosure and/or poor bed adhesion.

Notable Fan Curve Settings

If you are like me and don't want to just set your new RAM fan to 100% and forget about it, you can use Fan Control to set the speed of your RAM fan according to the reported temperatures of your RAM.  Fan Control is not normally able to see the temperature of your RAM, but with the use of HWInfo's shared memory support, you can use HWInfo to see the RAM temperatures, share them with Fan Control, and then set a fan curve accordingly.

Installation

The coolers are intended to clip onto the locking clips for the RAM on your motherboard.  Ensure that ALL of your clips are in the locked position before attempting to pop your cooler onto your motherboard, otherwise your cooler will not be able to seat onto the clips and you could possibly even break one of the unseated clips where you do not have RAM installed off.

Ensure that the latches line up nicely in the recesses of the cooler.  The recesses are responsible for keeping the cooler, fan(s) and duct(s) installed, and an incorrect fit could mean parts falling off later.  When installing the cooler, it will require some effort to install but should snap nicely into place.  It may be difficult to install if you do not have the latches properly aligned or they do not align.  It is easiest to install on a vertically oriented motherboard, where you can then install the bottom part of the cooler on the lower RAM latches, and then pop the top side on the upper RAM latches.  If installing the cooler with the motherboard in another orientation, you will probably have to push the latches fully closed to install the cooler.  The latches have a tendency to be able to wiggle out a little while in their latched positions.

Longer m4 bolts can be used to screw through the fans into the cooler, but an easier alternative with no threat of one day shorting something out is to run TPU filament through the holes instead and tie the fan to the cooler with the TPU.  

Intake ducts can be bolted to the fans with m4 bolts, but again, TPU filament is a good alternative for installation.
