External heatsink on Psu

[gt_addict]

Mods please feel free to move this if it's in the wrong section

Just a curiousity question really. I've got an rm1000 PSU and find its gets rather warm on the underside of the unit (opposite side to the fan) where all the sockets are. I've currently raised it with a large rectangular piece of aluminium but wondered if it was worthwhile sticking a heatsink on the bottom with a fujipoly thermal pad?

What do you guys think?

Put it on a grill with the fan pointed down.

The hot side will point up.

Target sells a cheap grill for 8 bucks. edit > $6.49

I have a link give me a minute

with fan pointed down  it pulls cooler air from below.

you can try an infra red gun to find the hot spots

Nice one cheers Phil. Wouldn't be able to get the grill as I'm in the U.K but I'll have a looks at similar shops when I get a chance and see what I can find.

Would the heatsink work so you think or should I not bother?

I have that psu. And the lift from the grill. Helped.  I also pointed a 20 inch box fan at three psu's sitting on that small shelf.

 Last thing the  psu is noted for overheating so try keeping an eye on it.

Oh I do keep an eye on it. Don't want any fires lol. Its running 2xS3's at 243m so not like its massively taxed and my room is only abour 18-20c ambient so not hot in here either. Just wanted to try and prevent any issues while I can.

No need to cool the PSU. If for any reason it gets too hot, it will just shutdown.

Inside a computer case a PSU intake is very hot and it doesn't have issues so with your PSU being outside in the open air shouldn't be a problem.

that psu has been know to have thermal heat failure due to not shutting down.

I will find some links

So just the RM750 and RM850

What about CX750?

Phil is pointing you twords an amazing tool I use one similar to this more often then I ever thought I would.   So nice to walk in mining area and get reads around machines and see my CFM's get maximum effect.  With summer heats coming (and raising some already) I use it more and more.  

I'm surprised on RM series I have 2 RM1000's and they always worked fine for me no heatsinks.  So not sure if made nicer then smaller ones or what.  But I have had them for quite a while with good luck.

rm1000 is very good gear but  it is pretty hot in one spot.  I mine with it in a pc 2 r9  390's  doing eth coin  pulls 550 watts.

case has a lot of air flow so it is all good.

Mines running 2 S3 oc'd to 243m, 2x u3 and a rbox 110 running 200m for now.

Phil is bang on there's one spot that gets warm. I'm going to find a rack and mount the u3s and PSU on there with a couple of fans underneath to cool it all. Just got to find the time to get the rack and change the set up

[gt_addict]

Well finally managed to get a rack today. Had to go to the kitchen section of the supermarket  3 tier stackable wire rack. Heres the set up:-

Base level under he first rack is open.
First rack up has a 120mm fan on.
Second rack has two U3's on.
Third rack has the rm1000 (fan facing up) with the a gecko stick as the cherry on top keep cooling thanks to the rm1000 fan.

The u3's and psu are staggered so the 120mm fan blows onto the u3's and half the hot side of the psu, plus the u3's draw air down from the other side of the psu.

Sound ok or should I have the fan facing down on the psu?

I thought hot air rises to more chance of the heat being forced out the back of the psu if the fan is facing up

I could just be lucky then I have had mine since GPU mining day's long ago.  Eventually they mined asics, but that have lasted a long time.   They have went through winters, summers.  Mining in house and mining in a mining area.

I never had a issue with all that so I still think a good gpu.  Although I admit when getting PSU's later on I got the EVGA to get 1300 vs 1000.  And now it's all about the server psus.

I have similar experience with Fortron 500W-750W single rail series. All of them have insufficient cooling of synchronous mos-fet rectifier, so they blow before any protection shut down the PSU. Thery also put plastic insulation sheet from one side, so overall airflow is poor. Only solution is keep load at 12V less than 80%. They have 5 year warranty so opening PSU and reworking power mos-fets and heatsink is not useful.

Sometimes I buy used PSU for about 50USD and RMA my failed. They always return full price instead of repairing my PSU.

yeah running atx at 50 to 80% works for many pieces of gear.

A lot of atx simply can't do 90% or more at a 24/7/365 pace.
