How Do I place a fan on a 3d card with no connecto

[Untruest]

I am interested in putting on a fan on my Radeon 7000 but my card doesn't have the connector for it. So i was wondering, how can I give the fan power if the connector isn't there?

you might have one free on your Mobo...
Or use an adapter from your PSU...

Use a fan with a 4-pin connector. On cards like that, when I need a fan I just screw a 40mm CPU fan to the sink and plug it into the power supply.

I don't have a system fan, so that connector is probably free. Would it be possible to see the fan and the connector from the power supply in a pic? I am not sure if you mean a fan able to plug in to the large connectors like a hard drive or the small one like a floppy.

Normally when you buy fans, you have a choice of 3-pin or 4-pin style. 3-pin plugs into the motherboard, 4-pin plugs into a large hard drive style plug. You could use either.

If you use a 3-pin with the fan-speed detection software for your board, you can detect the fan speed for that fan.

Unfortunately for me, all my fans are either 4-pin or 2-pin. 2-pin fans were once used by major OEM's to attach fans to the motherboard without speed detection, and it's from those types of systems I got most of my fans.

I did a little research, and found some 4-pin fans at a near by store. The heatsink on my video card is about 45mm so should i get a 40mm or 50mm. I think 40mm would make more sense but i am not the pro on this topic.

Thanks for all the help guys, i appreciate it

Sometimes a 50mm fan will fit a 45mm sink, but that puts the screws very close to the corners so you might have a problem attaching it. I'd go with a 40mm fan.

40mm fans are also more stable (less tendency to wobble) for any given thickness, so at 10mm thickness for instance a 40mm fan will tend to last longer than a 50mm fan.

50mm fans offer increased airflow, but I doubt you'll need it.

CPU fans used to be mounted with sheet metal screws, screwed between the fins. This is still a good option for most video cards with passive sinks, so long as you choose the proper screw size.

All my high end 80mm and 120mm fans came from power supplies. SOME could be changed from 2-pin to 3-pin by soldering on a lead!

And my 40mm 2-pin fans came from OEM coolers on Pentium systems.

[mopeygoth]

true, afterall it's just a plug.. I have not tried soldering them to make pin-3 -(the non-existant) wire work, but it's possible? I have bended many motherboard fan-connectors by forcing them on, don't really care too much about it, as long as I am not selling them. I have the same experience, they are really really good most of the times.

heh, the good old pentium fans they fit almost anywhere

Yes, on some fans if you fold back the sticker you can see a blob of solder that's unused, and sometimes that blob of solder is for the tachometer.

I've gotten quite a few Deltas and Panaflows from OLD power supplies. I'm talking IBM XT compatables.

cool, i'll have to check that out. Hopefully they'll have some 3-pin plugs lying around at work.

heh, they used top notch back then huh?

Back in the 80's computers were made to last 15 years! And the weight!

it was beautiful *sign*. Despite the weight of the era, "LAN" gaming was easier, my C64 had two joystickports

So you want me to place an 80mm system fan in the case? I am completely clueless on what to do but i seriously need to o'c my card. BTW I can only hold a 60mm system fan. I going to change my heatsink to an aluminum or Magnesium metal since they have a higher specific heat capacity then copper. And i saw a fan that's 40mm and has a 37.5 CFM with 27DB is that good.

 

[mopeygoth]

sure.. put as many 80mm's in your case as you "can" fit. 37cfm seems quite allright for a 40mm fan, the 27dB might become an issue, depenping on how "they" measure it, and depending on how fussy you are about noise.

Changing the heatsink sound like a nice idea, just remember that the bigger fan that'll fit, the better. Just don't spend as much as you'd do just buyng a better used/new card.

Will watts ever become an issue with excesss fans?
I currently don't know how many watts my power supply has.
I used a formula from high school to calculate it using the voltage and amps on the back. Didn't make much sense.

 

[mopeygoth]

no, not really.

ok, thanks everyone
I think i got my answers with the help of research and u guys.

The next step is my heatsink,which i think is more important then the fan, but i'll post that in a new thread
