Enermax PSU

[eXtraktor]

You guys know those little holes in the back of the psu thats inside the case, on the opposite side of the fan? Im not sure if im clear on this, lol but theres some hot air coming out of those holes and into the case... could i just tape those so the hot air would actually get out in the back (fan)? I have 4 fans in my case (Antec) but its still hot, 31.2c in the case - cpu 100% load with an ambient of 24c. Id like to get those temps down so i can overlcock that chip.

????! Is the psu fan still working? Some of the Enermax psu's have a variable speed fan: if yours does it may be going to slow!

I would recommend NOT covering the holes: they should be the intake air for psu cooling. So no hot air should be coming out.....

I have had some old generic supplies that had the same problem though; I upgraded the fans to get the air moving better.

Be careful if you decide to try this: psu voltages can be very dangerous.

Unplug the power supply and let it sit for a few hours if you are going to open it up.

I have 2 fans on it, one at the bottom and one at the back. This is the one i have but what im talking about is on the other side so you cant see it. So even if i cover them up i still have an intake and the back fan. Should i still be worried though?

I have pretty much the same one; mine has the variable speed exhaust fan on the back, although I believe they have versions with and without that feature. If yours does, try turning it up, if not then you should be ok blocking the back- it will change airflow some, but I don't think it would be a problem.

Use the title of this post in the search function. You'll find some threads. Check the fan on the back of the PSU to see that its working. Mine would turn off a lot. So I found a way to fix it.

There are 2 styles of this PSU, one has a dial to control the back fan's speed, the other is temperature controlled via thermistor.

With the thermistor, I had to plug the fan into the motherboard. I also cut the thermistor off (a little nub on its own PSU wire) and reconnected the two wires so the fan goes at full speed.

You could tape up the vents on the front of the PSU. Might give better exhaust pressure since the PSU has an intake on the bottom already. But having more case fans with more cfm for exhaust and intake would be a better way to get cooler case temps. My ambient is 24C and my case is 28C. I have 4 case fans + PSU.

This model has fixed speed fans.

I tried it, i taped up the front of the psu with some duct tape and the airflow from the back fan has increased. The good thing though is that the temperature inside my case dropped almost 5c and the air coming out of the psu also is colder since the air in the case is... I dont think its gonna overheat because of the fan on the bottom keeping the airflow pretty good inside the psu.

Sounds good. What a buddy of mine did to his PSU was a bit more extreme. He cut out those front vents with a dremel and installed 2 60mm fans side by side to force even more air out the back of the PSU.

hey, that little sticker on the side of your PSU probably says the same thing as mine since you have a similar PSU:

WARNING: Air opening should not be covered

Just thought i'd point that out although its up to you if you want to keep it taped up or not.

"overclocking may damage the components" hehehe remember that one? Theres a fan at the bottom taking in cool air so im not too worried. In fact, the psu appears to run cooler because its not taking in the hot air it was spitting back in the case anymore. I touched it to see, and the casing feels colder than before. Im not too worried. In my other pc theres an Antec 300w psu and it doesnt have a fan at the bottom, that one i'd be scared to cover up the holes.

I've got the thermal controlled 350 enermax PSU and there is almost no air coming out of the back. I guess the PSU must be cool as a cucumber right now...

I taped mine over on my 350 EnnerMax, bad design if you ask me, with all the airflow from the fans it seems stupid to pump hot air back into the case...
