Is it a good idea to use a 3-pin connector pump?

[m26k9]

Hey guys,

I'm looking to buy this pump: http://www.jingway.com.tw/en/products_pump.html
Mainly because it is not easy to find custom water cooling parts and supposedly this is the same pump maker of Danger Den (not sure though)..

ANyways, whats bothering me is that the power connector is a 3-pin one which I need to connect to a fan connector on the mobo.. I am worried if this is a good idea..the connectos in the mobo are supposed to connect to a fan.. but this pump will draw about 6.5W..maybe more... so is this safe? will it make the mobo unstable.. drawing a large wattage (relative to a fan)? or is there anyway I can convert the power connector and plug it to the power supply..?

Cheers.

I would simply cut or remove the positive and negative wires from the 3 pin connector and use a regular 4 pin molex connector to power the pump. You can leave the rpm sense wire on the 3 pin connector if you want to monitor pump rpm's from the motherboard's monitoring circuitry and software. I don't like powering any fans (or other things) from the mobo headers that draw more than 3-4 watts max myself. I have had a mobo header burn out in the past, luckily it didn't fry anything else.

EDIT: Since that is a pump motor, I bet that startup current draw with it is at least double what it's running current draw is and asking a mobo header to pull 12 watts even momentarily on startup is too big a risk, IMO.

Thanks man.
Yeah seems like a bad idea to plug it into the mobo.. will use the 4-pin..

for a 220v motor that goes from still to max rpm i think it was calculated with the wattage X 3 to 4
i don't know if it is the same for that pump but i would imagine it is pretty close

Why not just using a 3 pin to 4 pin molex adapter? Most 120mm fans come with them, I have 5 or 6 spares laying around, but you won't have the RPM sensor via motherboard. You can also buy them pretty cheap http://www.newegg.com/Product/Product.aspx?Item=N82E16812189119 but shipping prob wont be worth it, unless you need other items and add them to order.

Thanks guys.
I'll probably convert it to a 4-pin and plug into the psu. Don;t need to know the rpm anyway...

one more thing.. I want to get a 2x120mm radiator.. a Black Ice one.. and want to keep it on the case.. but my pump will at the bottom of the case... would this have big effect on the water flow speed.. or should I get a single 120mm radiator and keep it in line with the pump..?
Cheers!

as long as the case is a "average" hight full tower case then it will be fine, hell even if it was double it would be fine.

though i will suggest a Swiftech MCR220 over the black ice series, but thats me.

Would like a Swiftech one too.. but not easy to find them around here...

i know that feeling of not beeing able to find the stuff you want around at your plce

[m26k9]

it is quite frustrating man.. and quite strange that its not possible to find these kinda brands in Japan.. and the prices are expensive too.. compared to Newegg... shipping from US (when available) takes about another $50~$60... :(

You could take out the rpm sense wire and plug that it into the motherboard and run the two remaining wires into a molex connector, that way you won't damage your motherboard and still have an RPM measurement.

You should try to keep it if at all possible, that way you have another way of checking the system is safe.

Edit: I think i have a few spare adaptors. If i can find one you can have it if you can't find one.

You could try sidewindercomputers for international shipping. You can pay by either paypal or credit card. Very responsive and pretty good service if you ask me.

Because the shipping quote is not very accurate, you may wish to email Gary and get a coupon to waive the shipping fee.

Another alternative is jab-tech, but that company does not ship to Asia or europe.

Thanks a lot mate.
I think I'd be able to find one... :)

I will try those two shops.. the problem is I don't have much cash to spend on the cooling..I just bought the whole system couple of weeks ago... since the things like rdiators are quite heavy, the shipping gets expensive...

Another choice you might look at for a radiator is to look around and see what kind of heater cores are available to you in Japan. See if you can find one with dimensions close to the size of a double fan radiator. If you were in the USA, the 1977 Pontiac Bonnevile heater core is a great choice, but I don't know what would correspond to that in a Japanese vehicle.

if you can find a brandcalled cooltec it's probably a rebagged swiftec rad
when i googled it myselve i just came to some other searchpages and some insulationcompanies
after asking if anyone here ever heard of it Axis posted this here one
[ Can't find a store that sells them but from all the posts from 2+yrs ago, it looks like they are rebadged Swiftech MCR QP rads.

hope this here helps

its not the watts that really matters, its the max amps the fans pull. Thats what kills the mobo (although amps watts and voltage are all tied together)

Thanks guys.
I think I will go with the Jingway pump and the Black Ice Stealth 120.
My temps aren't really crazy.. Idling around ~37C and reaches about ~50C while gaming..
Just that my BigWater is now out of the case because there is no room so I need to get a new setup so I can put all the tubes and stuff inside..

Thanks for all the help guys.
