If you’re reading this, you probably tried installing your PSU on the SFX-L bracket instead of SFX, and found that your 25mm top fans collided with the PSU plug. Your only option is to use slim 15mm top fans but the default mounting pins will not work.
There are two ways to mount slim top fans in the NR200 – (1) 3D print slim fan mounting pins, or (2) make up the extra length with silicon spacers. I’ll cover the second way which is using silicon spacers as it is a cheaper and easier solution.
Materials needed
You’ll need to purchase silicon spacers. They are typically used for making DIY jewellery to act as washers, and are available for a very low cost. In Singapore, they cost about S$2-3 for a bag of hundred. As this solution requires you to push the spacer through the mounting pin, you should ideally find one that has small inner circumference.
You’ll also need HDD grommets that was included as part of the accessories in the NR200 box. You need 8x HDD grommets for a total of two top fans.
Implementation
The order of prepping is as follows: (1) mounting pin, (2) silicon spacer, (3) fan grill, (4) HDD grommet. Depending on the thickness of the silicon spacer, you may require more than two. I found that using two 2mm spacers worked well.
Once you have prepared the above on all 4 corners, insert it through the fans on the top panel of the NR200. The HDD grommets and spacers will help prevent any vibration from the fans or fan grill.
The end product should be like the images above. You’ll find that the mounting pins still protrude from the corners of the fan. However, this extra length coming down from the fan does not collide with any components in the main body of the NR200, allowing you to install your PSU in the SFX-L bracket.
Hope this helps!
