Memmento Mori Glad that you are interested in this not very common topic

I used the following product GYEON Q2 TRIM as my friend is using it on his car and is more than happy with the result.... What will be the result on a PC fan is the friend also curious

Anyway I want to test it also on 1 Noctua fan in my synology NAS for 2 reasons:
1, The blades are not high polished and have a more common surface than the NB eloops
2, The fan spins 24/7 so the result should be faster than I will have with my PC as i dont run my PC 24/7..

And yes only time will tell

Im just looking for a way to make the cleaning easier. Im using an duster but anyway the finest dust sticks with the fan blades and creates an white/grey layer on them (mainly on the backside of the blades), you need to wipe it of them.... For cars are plenty of hydrophobic coatings for plastic parts and you basically just need to "shower" the dirt of it. For this reason I used on 1 fan the hydrophobic coating and now letting the fans get dusty At this moment im using NB Eloops which have high polished surface of the blades. What I noticed is that the coating repaired the micro scratches on the surface. After some time I will make some photos before the dusting and after it, to compare the results without wiping just "blowing" the fans.

Would be glad if you share you experience or thoughts...

And I hope it is not much off-topic to post it here

All the best.

Intersting bit of testing you are doing.

Look forward to seeing your results and finding out what you are treating the blades with. My guess is it will help keep dust from collecting. That or it will increase dust collection.
Only time will tell.

Considering this thread is about cooling, what are you doing? Hooking up a 12V high current car fan to the PSU?
It's all pretty well explained in last few posts. 8 fans, 3 of them NF-A14 IPPC to be powered and controlled with 2 Gelid 4-to-one PMW splitters with PSU power. 5 fans on 1 splitter and 3 NF-A14 on other.
So while adversary is being overly worried about the 3-5 times more power fans draw at startup or if impeller is stopped, trying to figure out and optimize the problem is a good thing.

Seems PERIF is a ghost.

I gave you links showing most if not all power cable ends used for motherboard, GPU etc as well as pinout and amp ratings.

So far as I found, these PERIF connector on PSU should have more amperage than SATA connector. You can also take a look into link you provided.

As PERIF to Molex cable is pretty short, and spin up time of fans is just moment, there should be no problem using 18 AWG wire I think. Even if fans take 10A at this moment. After that, fans work at 2.15A (if pushed to max) and it is safe.

I just need to dig more around to be 100% sure about that PERIF connector if that will be choice of use.

Because I ordered 2 sets of Gelid 4 way splitter. Idea is to run 3X Noctua Industrial 140mm 3000rpm, which are rated by Noctua at 0.55A, on one Gelid splitter. On other Gelid splitter, I can use 5X (5th fan with Y splitter) Noctua Industrial 120mm 2000rpm, which are rated by Noctua at 0.10A.

Now, all these 8 fans draw 2.15A total as rated. Now multiply it with spinup higher demand and we have....?

If I could somehow know is my PERIF connector and cable are capable, than problem would be solved. Just connect Molex from Gelid splitter connector to each Molex connector which PERIF provides.

So, option can be PERIF if I can get 100% info how much amperage it provides (it is allegedly for older HDD-s and such, maybe they really provide more).

Other option - if I get you right? To use VGA to Molex adapter, and use VGA connector from PSU.
