Is this safe?

post #1 of 9
Thread Starter 
The fan that came with my Corsair CX430 was way too loud so I took it out instead of replacing it. My computer has been like this for around two years. Just curious if this is really dangerous or am I okay considering my specs?

If it's been like that for two years, I doubt you would start having a problem with it now.

I'll be upgrading to Haswell/Broadwell soon, just making sure my PSU wouldn't fail. thumb.gif

If you plan to build a system with high end parts you should not keep that CX430 anyway

It has a fan because the parts aren't specified to be able to run in the kind of temperatures you get without some forced airflow. But I guess it depends on your case configuration. Stock Antec 300 may actually help the power supply out because it must be mounted at the bottom with the fan opening on top, and the case has negative pressure with 120mm and 140mm fans on back and back top, meaning those should draw air through the back of the power supply up through the top (as well as from the front and side). Of course, that's still nothing as good as having forced airflow from the power supply fan that it was designed to run with.

However, some rather ordinary power supplies seem to run okay fanless until about 20% load or so (which is where you're at with E3400 and GT 640) like current Corsair GS or so, but those are a little better than CX.

Just consider that you've been stressing a mediocre-quality power supply hard the last couple of years. Haswell or Broadwell may not mean more power consumption on the CPU side, especially if you don't overclock and especially if you get a dual core, but larger upgrades on the GPU side may not be the same. I wouldn't trust expensive new hardware to a compromised power supply, and I wouldn't be surprised about impending failures, even with the modest power draws you're seeing, considering the quality and position of some of the capacitors and lack of airflow to them.

Doesn't have OTP. Most cheaper power supplies don't. And if the fan was being too loud, that was probably from the thermistor for the fan control essentially giving bad readings.

You've probably been able to get away with no PSU fan because of the air flow from the case fans, but generally it's a bad idea to run a PSU wihtout a fan because internal temps can go way up when there's no forced air flow, as SilentPCreview.com has demonstrated, and the CX430 doesn't have the biggest heatsinks. Also the CX430 isn't built with the best capacitors but with Samxon brand, which apparently doesn't like heat, as demonstrated by LaCie's recall of the AC power adapters for its external drives beause of that.

I have an old Ultra PSU (by Wintech) and asked Ultra if it had overtemperature protection. They said it didn't but that it wouldn't burst in flames because at around 55 Celcius the maximum power capacity would start cutting back enough to prevent that. Assuring.
