Direction for 3-wire cpu coolers.

Post by ~~~^^^mercury^^^~~~ »

most of the pieces are in place for my first bp6.
it happens to be a v0.41.
1) what is the significance of the v0.41?

have matched 2x 466s and 2x366s

will start with the 466s @ 466, then hope to go to the 366s @ 550

2) what brand and model number 3-wire fans are ya'll using on these cpus?

the 466s came with 2-wire fans
3) do i understand correctly, these 2-wire fans won't provide speed readings to the software monitor?

otherwise, have a 486 fan on the BX.
have a single 80mm front fan.
4) do i care if this front fan draws into the box or blows out?

there is a lot of ventilation grid on the back of the box, but no fans.
the upper vent grid has 8 holes for mounting 2 items,
one above the other, with 50mm hole spacings.
5) are there fans to fit this apparently 2 unit vent grid?

have a new 550w psu (power magic - not expensive)

6) am i overlooking any of the required cooling needed for 2x466@466?

7) ditto for the 2X366@550?

thanks,

1. Significance is that it is not a 0.40 version :) I would simply start out with the 366's. Run them at that speed and once you feel comfortable with the board, oc them to 550.

2. Doesn't matter. There is a standard contact on all fans so you just need to check for 3 wires.

3. Correct.

4. It depends. Some fill their boxes with fans but I don't In my opinion, the BP6 doesn't get that hot with 2 cpu's and a moderate graphics adapter. If you use a single chassi fan then use one that blows out air.

5. Fans run in standard sizes, 40mm, 50mm, 60mm, 70mm, 80mm and 92 mm.

6 & 7: use good coolers on your cpu's. Put some paste between your BX cooler (the green one) and the BX chipset. If you wan't to overclock to 550 then consider buying a larger heatsink for the BX or even a fan that sits on top of the current one.

thanks purrkur :)
just what i needed to know.

so i read from your reply,
the v0.40 and the v0.41 are without significant differences -
at least nothing i need to be concerned with.

the new psu is enroute.

bx is pasted and fanned.
(took the precaution of writing down the info off the bx,
just in case there is more than 1 used among bp6s)

graphics card is ATI RageIIC

right now the single 80mm box fan is blowing into the box
will see if i can turn it around.

further demystifying these wonderful tools, but
plenty of mystery to last the rest of my life.
i like that.

3-wire fans

Post by ~~~^^^mercury^^^~~~ »

purrkur,

found the cpu fans needed.
local computer shop had a box full of used fans.
sorted them into matching units.
asked assistant which matched set worked best on 370s.
paid $10 for a pair of StarTech ball bearing units with 39mm tall heat sinks, and
should be good to go.

thanks again,
~~~^^^mercury^^^~~~

p.s.: now for the real work - plugging it in and watching it go. :)

Just watch the cpu temps carefully because I got no faith in 40mm serving as the only fans on your CPU's. 40mm fans are not built to move a lot of air. Watch the temps especially during high load.

Fan size

Post by ~~~^^^mercury^^^~~~ »

thanks purrkur,

i apologize for sending a confusing message.
the fans measure 50 mm between the screws (70 mm diagonally).

i was trying to say the height of the heat sink is about 39 mm.
the fan then screws on top of that, of course.

i took the shop attendants word for it that this matched pair of
working fans would fit socket370. The base plate of the heat sink measures 60mm by 62mm and there is interference with the handle on the 370 insertion plate. but, if some of the aluminum is machined off along one edge of the bottom of the heat sink, looks like they will fit. and, the machining is easily done. hopefully the extra surface area on the bottom of the heat sink will just serve to better move the heat away.

the currrent fan running in this box (the box being typed on now) is a 40mm on a 366 SL36C on a slocket of a SOYO mobo. that is the board that is coming out and the bp6 is going in. the psu should arrive monday or tuesday. the fans will be machined by then.

let the fun begin.

by the way, the matched pair of 366s are SL36C. the info looked at so far indicates these should be fine for ocing to 550. think i will take your advice and just run them at 366 until everything checks out - then move them on up.

question: is there a progression for stepping them up, or
do i just jump from 366 on up to 550, in one fell swoop?

thanks, ~~~^^^mercury^^^~~~

set 100fsb/CPUs at 2 volts and see if the system boots into the OS. If so try drop the CPUs to 1.9 volts. Many BP6ers have had success and this will reduce some of the heat from the processors.
There are *almost* no bad BP6s. There are mostly bad caps.

I agree way too small to cool a CPU. I wouldn't even consider trying to overclock this thing until you get better cooling. If you have a staples nearby you could go there. They have Antec coolers that would be just perfect for what your after.

50 mm fans

Post by ~~~^^^mercury^^^~~~ »

bill,

the fans are NOT 40mm, actually
they are 50 mm.

i unintentionally sent a confusing email about the sized.

the matched 50mm fans:
* EVERCOOL
* ball bearing
* 50 mm (measure between mounting screws, along the edges)
* 3-wire
* "Low noise."
* "Long life time."
* 0.17 A
* 2.04 W
* Model: EC6020H12C

would you be comfortable with these 50mm fans?
of course, i will still watch the temps.

thanks,
~~~^^^larry^^^~~~

One other thing to consider doing, install your OS before you OC the board. It's best to install the OS when your positive the machine is rock stable. Only time you can be really sure of that is when it's running at spec.

About machining the heat sink...

Post by doncaruana »

Like others, I'm looking for a new heatsink/fan that will fit between the caps on my board. The ZIF spec is 61x56 mm and I've got a decent fan here with a 61x61 heatsink. When people talk about modifying their fan to fit, etc, are they just talking about cutting down that heatsink? If so, what kind of procedure is that? I mean, can I just take my grinder to it (taking ~2.5 mm off each side) or is there something special I would need to do?

Thanks.

doncaruana,

that's pretty much what i did.
put the heat sink in a vice, bottom up, then
used a hack saw to cut in, up to and just into the fins, then
rearranged the heatsink so the side faced up, and
cut in, through the fins, to the previous cut.
left a nice notch along that corner.
then, just blew it off with an air compressor, or
i could also have touched it up with a fine file.
did not think of that last one in time.

so, that got it past the caps, but
the lever for the ziff needs pryed out a bit to move it up and down.

for the hack sawing, i did work up a little sweat,
not that i mind,
fyi, it was about 1200 strokes to remove the 2 bottom corners from
each of the 2 heatsinks.
