Jeantech fan replacement

AHarvey · 18 Jun 2015 at 20:22

Hi all,

I've a Jeantech JN120F-600AP12v2 PSU and I woke up this morning and noticed it sounded really rough. Had it apart tonight after work, cleared all the dust out and although it doesn't sound as bad, it's still too loud.

It appears to just be wired directly into the PSU cabling so no easy replacement.

Would just buying a replacement fan, cutting and soldering/taping the wires be acceptable? Any suggestions on replacements or just a cheap one from here?

I believe its a 120mm fan that i need.

I would personally invest in a new quality psu!

you don't need new fan, you need new PSU.

This PSU has been running in this case for over 4 years pretty much 24/7 and never had a single issue with it. I know the rep that they have but I can't fault it and I'm not going to blow £100+ on a new one when a fan can be put in for a tenner

It's already lasted longer than the £200 model that I had in before it.

However, once the new office is built and I need to move everything down, I am going to look at some sort of custom case/desk build and then i'll be looking at new PSU, color coding and water cooling.

I have to admit that when I first started builing pc's many years ago back when I knew very little, my first psu was a Jeantech with a pair of 80mm fans. Since then I have had Hiper (uggghhhh), Enermax OCZ and a Seasonic die on me, some of them spectaculrly (Hiper) yet the Jeantech is still going strong. It's reverted to testing and loop bleeding now and is rather loud but it still works. It also weighs a ton which is a good sign. Cheap psu's usually weigh next to nothing.

That is more luck than jeantech quality.

I had no name psu running for 10 years with no prob but it doesn't mean i trust it.

I didn't say I still trust it after all this time.

It's only used for testing fans, controllers and bleeding/leak testing water cooling loops now.

So does anyone know if it is easy enough to replace the fan? The sound is driving me barmy

You would have to do it the way you suggested in your op. Cut both cables and solder them together. I would put a bit of heatshrink over each wire rather than tape.

Cool, do I need to look for a fan with 2 wires do you know or would a 3 pin fan be fine and just not connect the 3rd wire?

Yes, just leave the speed sense wire, usually yellow or blue.
You could alternatively connect it to the motherboard if theres a spare header.

I had a hiper PSU once. Sure looked pretty, but mine also blew up

Sirtec made Jeantech psus aren't all that bad tbh and will soldier on for years.
