Hello folks
Just breaking in my new x99 build and checking for teething problems.
I have a lovely Superflower Leadex Platinum 850w PSU, and I'm just wondering how hot it should get?
I'm certainly not overburdening it. It's a 5820K system with just one 770GTX.
I was playing Elite Dangerous just now for about an hour when I noticed some heat coming from the machine. I expected it to be either the CPU of GPU, but it was the PSU. Quite a bit of heat pouring out of it's back grill which was hot to touch.
I hadn't been looking at the PSU is a source of potential problems, but I'll be keeping an eye on it from now on.
Does that kind of temperature seem normal?
 
Er... No. If it's too hot to touch, that's way to hot. If your setups pulling half the rated wattage, the psu should barely get into its 30s-40s. This message might have gotten to you too late. I hope you have a fire extinguisher...

After testing further, I think I know what's going on here.
This PSU has a fan control switch. When set to 'Eco' - the default position - the fan doesn't spin at all unless a thermal threshold is hit. (I think around 55 degrees)
I think that's what happened here. I was gaming and the temperature was quietly building up but was basically contained within the unit. Suddenly the fan spins up pushing the accumulated hot air through the grill. I think that was sufficient to heat the grill and generally give the impression of suddenly high temperatures. Very soon after this the heat is dissipated and everything cools down, and then at a certain point the fan shuts off again.
I think that's what's going on.
Anyone else got a Superflower?

I have 1300w gold superflower. Well I never touched it to see how hot it gets ;) but I haven't pushed it far enough yet. Still working on my build. I may report back when the build is complete and I have put some load on it for an extended period of time.
 
Like all the Leadex range, your PSU has a semi passive mode. It will only spin up the fan when the temperature hits a certain level, rapidly reducing the temperature, whereby the fan will switch off again. This is to give you a relatively silent operation of the unit unless under a sustained heavy load. If for any reason you don't want this feature, flick the switch you've identified at the back of the PSU to put it in normal mode and the fan will operate normally.
 
I have a 750W Super Flower Leadex Gold and I'm not sure if the fan has ever come on. The PSU dust filter is always clean and the unit itself just gets warm when gaming, not hot. That's with an i7 4790k, Zotac GTX 980 Ti, 16GB DDR3 1866 RAM, SSD & HDD.
