eMachine celeron 500mhz

The cpu fan on my gf's wimpy emachine celeron 500mhz has become too noisy to ignore, and I'm wondering if I can't just disconnect the thing? Was a fan absolutely necessary for these processors?
 
Yes. Even the lowly Celeron proc needs proper cooling. Spend a few dollars on a good HSF and some Artic Silver 5 thermal compound and replace it.

Well, I (perhaps foolishly) ignored this advice and unplugged the fan. 24 hours later the machine is still alive, with almost no noticable difference in the temperature of the air coming out of the back. (it went from fairly cool to very mildly warm) The only fan in this 500 MHz eMachine is now just 1 inside the power supply, which seems to be doing a decent job of drawing air up and off the little celeron. And it's significantly quieter! I will update this thread if things take a turn for the worse, but so far it seems to be working fine fanless.
 
You can't rely on how the exhaust air feels to know if the CPU is too hot.
Truth is even though the CPU isn't as fast as newer ones, it's still made on an older process with bigger traces pushing more volts and it will get hot!
 
I just upgraded an HP computer with a Celeron 700. It had no fan on the heatsink and no ducting or anything and it ran fine all day long that way. The heatsink was a bit taller than normal, though.

I put a P3 1Ghz in it and added a new HSF to cool it.
 
Heh. You guys are funny.

I have a C500 system running passive. Came from the factory like that.

Run Prime95 to create a massive heat load and see if it survives.

I opened up a pentium 233 recently = turns out the person who built it didn't connect the cpu fan! For probably 4 or 5 years, the cpu must have been sweating. I had to open the case for another reason, when I told them, they said 'what fan?'.

I connected the fan

If you are lucky [and you were very] running a 500mhz like you have without a fan, maybe you should buy a lottery ticket
 
I should be clearer. The Celeron 700 had a passive heatsink on it, not a heatsink that was missing it's fan. It was fine.
 
i can see how it would work - as long as the case fans were very efficient - but i'm surprised that the 700 came like that. For a 700, there is no way that i would risk it, but, whatever............

that is hilarious... checking the exhaust air to see how hot the cpu is... thanks for the chuckle! by the way, if it is making all that air "very mildly warm", there must be a heat source right? there is! it's the cpu that is running at about 70C! 😀 put on a fan my man.

The mobo/bios does not appear to have any temp monitoring. How else would you suggest I check?

I'm not yet the geek I wish I was ... 😱

You can try Motherboard Monitor, but your motherboard may not be supoorted for temperature monitoring.
 
I don't think motherboards from that generation had CPU thermometers. If you can get an infrared thermometer, that's probably the easiest and most accurate way to check the temperature. Otherwise, see if you can get your hands on a multimeter that has a temperature sensor (it'll look like a little melted ball of plastic on a wire). Apply that directly to the CPU and it should read just a little below the actual temperature, due to the top side of the CPU being the cooler side and the sensor being exposed to ambient air on one side.
 
The Celery 500 was still the Mendicino core PII Celeron an at 500 they ran fairly warm. To be safe I would replace the fan. It will not cost much and you will be safe. I have seen passive cooling on some factory systems but it was a much larger HS and had very good cooling and in some cases ducting over the CPU. with the 500 and 533 I would use a Fan. Up to you. I have a friend with a 533 Celery with that same core and in the summer with very large HS it gets a bit warm. His Abit BM6 has full temp monitoring and it runs in the high 50's C if he is doing Video Encoding and he has good cooling in his case too.

Be safe and replace that fan. Since the system came that way with a Fan I am sure it has a smallish HS and needs the FAN.


 
(The following is sarcasm and is not to be taken any other way...)

No, you don't need a fan to cool down that hot processor. They only put fans in there to annoy you!

(End sarcasm, please pay attention to the next bit...)

Yes, you need a fan.

Would you operate a car without a radiator or coolant?

If it shipped with a fan, you need a fan!

Sorry MW. you can also check in your BIOS, under Hardware Monitor.
 
OK, you guys have scared me into plugging it back in. :disgust: I suppose I'll just buy a new quieter fan for it... Any recommendations to fit this CPU/heatsink? While I'm at it, maybe I'll also replace the fan inside this miniature-sized PSU ... but I'm not sure what will fit/work for that either. Any advice? ( and do PSUs store a charge? :shocked: )
 
Most power supplies have warning labels on them for a reason! Yes, there are capacitors in there and yes, what you don't know CAN hurt you! 😉
