New P3 .... cooling problem

[Holst]

Ive finally got my dads P3 450 running.

I had to buy a UDMA100 controller card to get the hard drive working right.

ITs now running win2k just fine

In my big case I used to run this chip at 600mhz (133fsb) no problem at 2.2v

It will post at 600 but overheats due to the small case its crammed into.

Im not sure if anything can be done or not.

I tried reversing the CPU fan but it made it very loud

Heres the case

With the PSU removed you can see where the chip is jammed in.

THe PSU gets so close to the heatsink that it touches it..I had to put some electrical tape between the two.

You need a bigger fan on the heatsink . . .

The chip itself is a P3 - 450 katami 100fsb.

The heatsink is a £5 taisol thats glued to the core using arctic silver adhesive (permanent)

The Black heatsinks on the cache chips where cut from the old Intel stock heatsink and are glued in the same manner.

On the left you can see the green tape ive used to cover the pins on the CPU to increase the voltage.

Its currently set to 2.2 as the motherboard will only run up to 133fsb ive never needed more (ive tried up to 2.6 for fun)

I'm glad that the IDE problems are behind you! Those shiny interiors look kewl--but a little electrical insulation in the way of paint seems a good idea, imho.

Personally, I'd put a fan that's more enthusiastic on the P3's heatsink. There's plenty of aluminium there, it's a shame not to take advantage of those fins.

YS-Tech 60mm 26cfm is in the post

I think the case might warm up inside as the airflow is a bit poor.

If it does ill put an 80mm blowhole on the top and one in the side to get some air flowing near the heatsink.

as Dimm said... you NEED a BIGGER fan on that sink... that will help alot...

secondly... looks like a PS mod might help if the other side of that PS (the one not show) doesn't have ventilation... the PS being on top of the HSF can help if it has an opening AND is moving significant air itself...

just my 2 cents...

I got the new fan today.

Im glat www.theoverclockingstore do free postage as that kept the cost down.

This looks allot more meaty

Thats more like it, Holst! Time to put the puppy to work.

Looks like a Delta Screamer, TM. Good choice, but armor your ears in advance. Didn't the older Screamers have blue tach wires?

Its a YS-Tech 60mm
Not quite as loud as a delta...but still a tad annoying.

Unfortunately it still wont run 3dmark stable even with the case off and the PSU on top.

So I dont think its a cooling issue after all.

Ive not checked anything else yet...maybee my dad has altered the memory timings or something stupid.

Also the G400 thats running in it got very badly overheated once and that may be the cause of the problem...it gets slight artifacts and errors even when its not overclocked. I think the memory is damaged.

Yikes, same style of case as mine. The verticle PSU really sucks, I'm running a socket board now, and trust me, slot-1 is better for vert. PSU's. Well, what I did to cool my slot-1 setup, move your cd-rom up to the top bay, and under it in 2 empty bays take some tape, cardboard and an 80mm fan. Install the fan in the 2 bays so i blows air towards the CPU, and then put it in place with tape and use cardboard to finish. I originally did this with one of the bay covers off, but later I just taped a bay cover on from behind, but tilted it so air could pass through. Sorry for the pic quality, but all my other pics are backed up on my scsi drive which is not powered up now.

Yes my case is very ugly when it's naked.
