Prototype LF 92mm > 120mm 3D printable adapter for L9a-AM4

[Kmpkt]

Hey Guys,

Title pretty much says it all. I would like to make an adapter plate to attach the Noctua 120x15mm fan to the L9a. Seeing as the L9a is 92mm x 114mm I figure a fair amount of cooling is being left on the table using the A9x14 fan. Furthermore the throughput on the A12x15 is significantly more I am hoping this combo could provide significantly better cooling for AM4 in the S4M. For the record I am looking to use this on the AsRock X470 Fatal1ty. I'm willing to pay via PayPal for your time depending on rate and quality of work. Cheers!

L9a-AM4 Heat sink height is 23mm so if you install 120mm fan, max RAM height is about 8+23-3=28mm, lower than standard RAM.

maybe pushing the fan to one side could resolve that?

Yeah the plan is that the fan would be offset so sat against the RAM like the 92mm fan does but then extended further back towards the rear IO than the stock fan.

eedit:

also, how tall could it go?
its 21mm on this model I just sent. 2+2mm from material and another 2mm for screw clearance and 15mm for fan

Hey KMPKT,

I have already designed one, I sent one to Josh for testing.

It ended up being 3.7mm tall, just enough to clear the Ram. It improves temp only in conditions that the air is recycling. It does give a quieter sound signature.

There is still a couple adjustments I need to make for user friendliness. I'll have a commercial release soon, but if you like to order an early sample, please PM me.

I know this is an old thread, but did you end up releasing this? wouldnt mind installing a larger fan in my case

 

[Thehack]

Yes I did.

I just sold an early sample of L9i version to a person in Germany, who has been bugging me for a while.

It will have compatibility issues with any large VRM heatsink, which seems like most motherboards today.

I will need to batch this and stock them. It'll happen at j-hackcompany.com whenever. 2-3 weeks?

Awesome!

What's the angle of the left side of the duct? It looks like it might be too sharp to really help with the airflow, have you considered making it just a frame on that side and letting the air go over the mobo?
