What voltage for a quiet psu fan replacement?

Post by thesofa2 »

What voltage fan do I need to replace the noisy fan in my TT030 psu?
TT030 with Storm with 256 Mb Ram, Thunder with a CF drive and Lightning, HxC floppy emulator and one of Codekiller's magical Mono/Colour switchers, 1040 STE, also 3 STS one has TOS1.0 AND 2.06 switchable with an HD drive, the other two are untested as yet, just bought for spares!!

There is an entire thread literally right underneath this one with people discussing replacement fans for the TT, have a read: https://www.atari-forum.com/viewtopic.php?f=88&t=40746

I read that and searched for Noctua NF-A6x25 FLX and found a 12 v one and a 5 v one

You can run the 12V fan on 7V to make it even more quiet. Use +12V as the fan+ and +5V as the fan-, it's a very old casemodding trick.
Only do that if the TT030 isn't full of extra add-ins like a VME graphics card, they do add up in power consumption and PSU heat.

People might want to hang me for this, but you could remove the plastic case fan grill and replace it with a 6x6 metal fan grill. It will greatly improve airflow, just take your time to do it nicely.

I have 4 TTs and every case was modded before i got them. So, it is very common to remove the grill

Indeed! Be careful, it's not that easy to find a replacement PSU for the TT PSU and if it fails it may ruin the motherboard! The TT PSU needs the airflow!
