took out that itty bitty annoying fan from pIII 600!

[Enemy Down!]

omg that stupid little fan made so much noise, right from the start when the system was brand new.

i took it out and am wondering if it will ruin my cpu?

it is a BX motherboard with a slot type cpu, a pIII 600

that little fan is so small, made me think if it did any good.

i am basically going to use this machine to host a gaming server, so the cpu load will reach up to 50% and probably stay there, as my server is popular.

i am wondering if it will be ok without that stupid fan on it?

the power supply is directly above it sucking air from inside the box and spitting it out from the rear.

Is it a Coppermine or Katmai chip? Did you take the entire heatsink off or just the fan? I'd be curious to know your load temperatures... it would help us to know if it'll be ok or not... if we don't know that then all we can give you are somewhat educated guesses.

Hi,

In any case you are pretty safe with a P3. Instead of burning itself if overheated, it will just 'lock up', thanks to the thermal diode, as long as you did not remove the hs, but only the fan.

So, I think you've got 99% chances of this NOT being OK. The efficiency of a HS is much much reduced without a fan... unless you have real good ventilation in the case, so I suggest you v-mod the fan to work at 7v, but leave some air there or you will start experiencing some serious problems!!!

Without seeing load temps, I would tend to agree. I recommend this (http://www.overclockers.com/tips615/) mod for a Millennium Glaciator heatsink. It's not easy, but the Millennium Glaciator is a nearly silent HSF combo, and fairly cheap too.

y dont u try and take it off and see wot happens! i belive that Pentium have a heat measure that will shut ur system off if it overheats!

It is off... he's asking if it'll be OK, which I think it PROBABLY won't. Pentium 4's will throttle down to reduce heat at 70C, however, PIII's will simply lock up. It won't die, but a locked up server isn't good to anyone.

NOTE: That heat measure is usually available in the BIOS of a lot of motherboards. I would definitely recommend enabling this.

i only took off the fan, NOT the heat sink.

its a gateway computer for christ sakes, it aint gonna have a temp sensor in bios , thats asking to much from them :D


well anyway, i really dont want to replace the heat sink with another because this is a SLOT 1 based cpu and i am not familiar with how to remove it. but heat sink is pretty big and wide, although it aluminum and not copper.

i am thinking it would be ok, since the mobo/bios does not require a cpu fan rpm signature to boot, so there is no fan installed in the cpu fan slot on the mobo.

i am also betting that intel can handle the heat characteristics better than the amd chips, even this though is an older chip.

i dont know if it a coppermine or not, but i do know it has 512k cache.

i just need some input from you guys.

[jazztrumpet216]

OK, it is a Katmai then.

Well, if it's a Gateway without a temp sensor, then the only thing to do is just run it and see. Keep an eye on it, and if it locks up, then it doesn't work. Slot 1 heatsinks are a devil to remove but it is possible, if you decide you want to do that later, we'd be happy to help.

A good solution to this would place a case fan on the back of your case, and build a makeshift shroud that would direct air from the fan to your CPU. Get a nice, big, slow, quiet fan for this. Many, many manufacturers did this on thier Pentium II and III machines over the years. Notably, Dell and Compaq, and probably others. In fact, I have yet to see an OEM business-level computer with a heat sink on a slot CPU. None of my Dells here at work do, and they NEVER overheat. It's not much of a problem unless you pump a ton of voltage into them, and overclock them by quite a bit.

Despite what the hardcore overclockers say, there is no need for a fan directly on a Pentium III heat sink. As long as there is SOME airflow going past the heat sink, it will be okay. Any Pentium III is hard pressed to get past 70C as long as there is a heat sink on it.
