Two fans - advantage or disadvantage?

po0k

I was thinking of putting two Socket7 fans (40mm in idameter mabe?) stacked ontop of eachother over the heatsink on my P200.
Afaik the fan that fits the heatsink spins slightly faster then the other one. I was thinking of spacing them out with washers etc. and double the airflow.
i'd also be up for doubling the voltage and hence the speed of one or both fans. The motors might burn out though.

Also, the P200 is on a VX chipset. Can this be clocked higher then 200?

dunno

Sorry if that sounded like a smart-arsè response, but I didn't want you thinking I didn't care enough to post.
I wouldn't bother personaly, throw it in the bin and get a new one, after all, no matter how much you O/C it, it's still going to be a piece of cràp :P

The two fans are fine, but don't up the voltage

What do you need two fans with on a p200? they're relatively cool... compared to athlons

Dead{o}santa: shaddap, P1s are still very useful, you gaming muppet you. :P

I don't think you can get a p1 above 200/233.. after all, the pII starts at 200/233

Hehehe .. I use a P200 :P (Not too much longer, building my Athlon baby!!).

I've got this box running Q3A, HL(+mods +expanions), Baldur's Gate 1/2, and a few other hungry games running rather well. So as Phaxx says ... P200's are still useful! I second that statement!

P1's usually end at 200Mhz. There were (P1)233's released just after the first p2's came out, but they're far and few between afaik.

Stacking fans can sometimes give more airflow, most of the benefit will be lost due to turbulence, and interference between the fans. So you won't get near double the airflow.

I wouldn't go doubling the voltage, the fans won't handle that for very long. Just get a case fan and point that at the heatsink instead, and get rid of the 40mm fans altogether.

As for overclocking, the quality of your motherboard is the main factor. Most p200 chips are good for at least 225, if not 233. The mmx chips are good for up to 300, I have one which will run 266 for days on end. Since your chip is not an mmx, it probably will not recognise a 1.5x multiplier as a 3.5 ( hence clocking the chip to 233) so you will have to overclock by raising the motherboard fsb.

Try 3 * 75, and if it is stable, mess with the frequency jumpers until it boots at 83mhz fsb (set the multiplier to 2.5 first)

thats all for now, gotta run.

I know, I've got one here on my little LAN, P166MMX o/c'd to 233MHz... only gives about 15-40fps in Counter-Strike. :rolleyes:
My point is though... you could pick up a celeron 400MHz for less than you'd pay for the Disprin to get rid of that headache from fiddling with your P1.

P200's rock for a lot of things... anyone who says otherwise needs a kick in the teeth!

It is a rare thing to have a P200 with MMX...Intel only made them for about 2 months....I did have one which was not MMX and it would not go over 233 and at that, if it tipped 40 DegC it used to plop.
If it is MMX(probably), then as Gerry said, they will go 3.5 x 75 which will give you 266mhz.
P1's I) ARE useful 2) Dont normally get very hot.

Be careful about pushing your 75 FSB to 83 as yer PCI bus will be running out of spec and yer cards may suffer from this...PCI bus is specced at 33mhz BUS.

I cant stress enough how important air circulation is in a computer case...I see some guys leaving the case off saying that it will be cooler.....NOT! maybe the top edges of yer PCI cards will be cooler, but deep down by the processor socket, chipset and Memory modules(which are normally clouded in slack of IDE cables) is where things start to roast...

what you want without going to much expense is to keep the fan on the CPu, and buy an intake Chassis Fan and clean out the Chassis Fan in yer PSU...be careful of capacitors...also make sure that the PSU fan is blowing out and the chassis fan blowing...

Tie down any cables which may obstruct the intake airflow and always seperate Hard drives if you have another spare int. 3.5 Bay....

After this, you should be fine... :rolleyes: :rolleyes: :rolleyes:

OSiriS

Gerry is right there, there would be a slight increase in airflow, as air would be driven into the 2nd fan faster than it would normally pull itself.Turbulence would be an issue, and unless the bottom fan is well built, it mightn't handle the stress of the extra airflow for 2 long. To counter that you would need 2 fans constantly matchinfg speed, with their rotations slightly staggered, with the bottom fan leading (I think). Since a setup like this would be rather costly and difficult to implement, you would be much better off getting a new single fan with improved air-flow.

P200 (non-MMX)
Chaintech VX mobo (max FSB = 75)
Max Multiplyer = 3
hence 225Mhz.
I'll tubularise the IDE and floppy cables.
Done it allready on my P3
There isn't much else I can do i think.
I haven#'t yuet tried booting the box.
Its the same one I'm welding together with another and 2 Soundcard+IDE controllers for a mx of 8 IDE drives.
Can you have more then 1 soundcard+IDE controler ina system?
I'd only have a Lan card, S3 Virge and Voodoo in it.
IRQs shouldn't be too mich of a prob cos the Serials and parrallels will be disabled.
The sound cards are ISA.
Copuld cause conniptipons.
Gotta run.
