Using PSU as Exhaust.

I have a Corsair SF600 that has its intake directly facing one end of a GTX 1080. Since it can get fairly warm, I’m wondering how that will affect my long term reliability etc. I can’t really change it either since flipping it around just points it towards a wall. (Rajintek Metis)

The PSU's output figures are based on the unit staying within operating temperature. If the unit is hotter then as I understand it you will be getting less efficiency than the PSU is rated at. It probably also won't be able to deliver it's rated watts.

If you're interested in a product please download and read the manual first.

If the fan actually spins and makes an effort to exhaust the air it shouldn't be too bad.

 

However, if the fan doesn't spin and the GPU just throws hot air into the PSU it might be a problem.

If you're feeding hot air into the PSU that already barely supports your system, then that's a.. hm. well very sub optimal, I should say. You don't want that thing to run at 70C non stop when gaming and stuff..

Isn’t 600w more than enough to support this type of system?

The fan does spin up once I start using the system. It’s stays passive otherwise.

 

 

 

 

 

On another note, what can I realistically do? If I can even find space for a fan, where would it point?

For some reason he thinks that a <300W load on a 600W PSU is barely enough. It's plenty

Yep.

 

Get a temp probe and stick it in the airflow between the GPU and PSU.  If that air isn't over 40°C, you're fine for up to 600W.  If the air is 50°C or more (highly unlikely) you're critical and are killing the PSU.

The airflow seems to be about 47-51C with some fairly crude measuring. So, should I flip the intake around? There’s a couple of millimeters there, not a lot, but at least it won’t have hot air blasted into its intake.

ehh... I don't know what "crude measuring" means.  Not too hard to take a thermometer with K-type thermistors (costs < $14.99) and put it between the GPU and  PSU.

 

 

Crude as in putting a paper in front of the exhaust and measuring its temp with a thermal camera. Yeah it’s not ideal by far but I’m a bit time strapped and can’t get a temp probe. I’ll definitely do that when I get the chance, but this is the best I have now.

Measuring 51°C concerns me.  That's why I'm not at liberty to say "you're ok" without seeing a REAL measured temperature.

 

Since the paper is blocking the airflow, the temperature will rise.  So it's not a good measurement.  Odds are you're fine.

 

 

Hopefully so. I’ll just make sure to lightly use the GPU until I can get an accurate temperature measurement.

 

Thanks!
