Can I use my computer if my PSU fan dies???

post #1 of 15
Thread Starter 
Hey all,

My PSU fan just died. Well, okay, it didn't "die" - but it's slowed to nearly a halt and wont spin good unless I've got an object putting pressure on the very center of the fan. I think some screw flew off or something and allowed the fan inside the PSU to get too close to the cage and something f*cked up.

Long story short: If I have good computer circulation and good temps, can I still use my computer if the PSU fan dies?

Let me know ASAP before I do dumb things. I just spent like 2 hours trying to wedge random objects ranging from toothbrushes to shoelaces to q tips and a few pencils on the middle to keep it spinning to no avail.

Thanks

I wouldn't operate it. The fan is an important component of the PSU. They aren't quite made for passive cooling. If anything you are going to put more strain on it and the actual supply will die.

Well it's not something that couldn't be easily replaced by hand, if you fancy voiding your warranty.

But considering the fact that you speak of shoving random objects into something that can store electricity, it's probably best you don't go near it.

You're better off getting the PSU replaced. I wouldn't run it without a working fan.

I wouldn't recommend using it, as a power supply's performance and efficiency is inversely proportional to its internal temperatures.

I'd recommend replacing it with something like Rosewill's Capstone 650w, which is on sale for $64 shipped @ Newegg currently (with promo code RW20PPSU). It's a step up from your PCP&C Silencer, even when it was properly working. wink.gif

I just checked my temps. I've got:

System: 31C
CPU: 39C
AUX: 48C
SMIOVT4: 31C
SMIOVT5: 31C
SMIOVT6: 31C
HD1: 26C
HD0: 27C
GPU: 36C

Don't those numbers sound relatively on target for idling? I'm just sitting at my desktop not running anything.

Well the psu will function until it heats up and shuts your system down.

If you have good air flow on it, then it should be fine.

Are any of these temps a reading of the PSU??? Thats what matters here. More than likely, the PSU will continue to operate for a while, but whatever lifespan it had left is going to be immensely shortened.

The fan is there for a reason. If it was mine I would replace the fan myself.

If you dont trust yourself but are desperate to get it fixed, I guess you could rig a spare fan to the outside of the PSU housing, to at least get some airflow through it.

Are there any programs that can monitor PSU temps? And what temps should I be looking out for? Er, thresholds or whatnot.

As said before, the only temp sensors the program I have can monitor are System, CPU, Aux, HD0/1, and GPU.

Though it does seem to notate that the Sys Fan is at 0RPM.
