Jakalwarrior Posted May 9, 2004 Posted May 9, 2004 (edited) I just built a computer from spare parts for a friend. Its an old P3 500mhz. The thing has no fan though. It has a shrowd running from the powersupply down to the processor I guess to suck air past it. I tried putting in an 80mm fan to blow in but the computer acts like its not plugged in when so I had to remove it. Guess its the 200watt powersupply being weak. When I touch the heatsink its warm-almost hot. Ive ive never felt any warmth when from mine, its always ~ room temperature. Is this thing going to run hot and melt down?

Newport Posted May 9, 2004 Posted May 9, 2004 my old school had a computer lab with a crap load of P3 500 Mhz and i noticed that they had no fan on them either. In comparison, my old P2 400 Mhz just had that HS on it and that comp was on 24/7 no problems. I think the rule of thumb is that any processor that is below 1 Ghz does not create enough heat to place a fan on it. Correct me if i am wrong but that is what i have heard.

Um... if I didn't run h/s & fans on my Retro's (Celeron A's & K62's) they'd fry real quick as for the title of the thread..."Did Socket A P3s Run Cool?" Socket A wont support Intel processors, the last industry 'standard' that supported AMD/Cyrix/Intel was good 'ol SS7 Now, to the question... I've seen those shroud thingys on propriety built systems with a PIII-450 (never got a closer look though), but every PIII I've ever seen has had a 'heatsink/fan combo' built on (see below) Would it be possible to cut an opening in that shroud to allow for forced air induction? (to compliment the current fan/exhaust system)? <_< Share this post Link to post Share on other sites More sharing options...
Newport Posted May 9, 2004 Posted May 9, 2004 Thats very weird because all of our old P3s didnt have a fan on them. Just one of those big arse HS with a air scoop somming from the PSU.... I dunno. Maybe those were "special" computers Share this post Link to post Share on other sites More sharing options...
Iggy Posted May 9, 2004 Posted May 9, 2004 Depends of revision and speed of the P3. The lower speed Slot 1 P3s didn't come with a fan, but I think maybe the higher speed ones did. The Socket 370 P3s came with a fan stock in all cases as far as a know. The Coppermine, which was the first revision of the Socket 370 P3 produced quite a bit of heat in the higher speed versions, but the lower speeds had excellent overclocking potential. All Coppermines max out at about 1 Ghz to 1.1 Ghz. The Tualatin P3, which was manufactured using a .13 micron process, was an excellent overclocker, and I've heard that using phase change some people got close to 2 Ghz. I dont think the Tualatins produced that much heat because of the better manufacturing process. EDIT: Thanks for the refresher Taz-the first P3s were manufactured on a .25 micron process, and the Katmai core ran VERY hot. Overclocking the highest speed grade (600 mhz) often required heavy duty cooling (peltier), and the it was still difficult to get a 650 mhz. Try to stay away from these. Also, if the heatsink is getting hot, that means it's doing its job. A fan wouldn't hurt though. Share this post Link to post Share on other sites More sharing options...

Maybe those were "special" computers Hmmmm... <_< possibly just a different flavour I should have said 'most' not 'every' because, now that you've described the appearance... I have seen one like it... but someone had still added an extra fan to it Not to forget slot 1 (like above) and socket 370 (like below) were still PIII's though having different micron process construction 0.25 vs. 0.18 Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted May 9, 2004 Posted May 9, 2004 get a 60mm , my mom's dell socket p3 has a HSf like amd's stock , but it never's gets hot Share this post Link to post Share on other sites More sharing options...
KraZy Posted May 9, 2004 Posted May 9, 2004 I tried putting in an 80mm fan to blow in but the computer acts like its not plugged in when so I had to remove it. Hmm.. what type of mobo is it? I know alot of the older Dell computers I work with will not turn on if the right CPU fan is not plugged in... Share this post Link to post Share on other sites More sharing options...
Guest FxXP Posted May 9, 2004 Posted May 9, 2004 A majority of Dells and Compaqs didn't have fans on their Slot 1 based systems. They came with a passive heatsink that was fairly large enough to dissipate the heat without the need of a fan. Share this post Link to post Share on other sites More sharing options...
Shadowfactor Posted May 9, 2004 Posted May 9, 2004 like i said get a 60 mm and hotglue it to the sink Share this post Link to post Share on other sites More sharing options...
Jakalwarrior Posted May 10, 2004 Posted May 10, 2004 Hehe, I cant remember the name of these old chip interfaces Knew it was a slot something. Anyway, the big problem was it wouldnt switch on if I plugged in an extra fan :/ The powersupply would just ignore me hitting the button until I unplugged it. Would that be affected by the fact that I made spliced wires to make the fan plug? (I took it out of an old power supply). It was running for a little while though then it got like it is now.
