Use Video Card without FAN?

Hi, do you think is safe if i use my very Old DELL PRECISION 470 with its Nvidia Quadro FX 540 video card BUT without its video card fan?

The thing is that i took out the fan for cleaning and i broke the 2 cables at the weld...

Will it be safe to use the PC without this fan? I will not do any work on it, i just need it to be on to be able to access to files during the day, I need it to be ON from as low as 1 hour to 8 hours tops per day. That until i get my new GPU upgrade that i will order soon....

I can also keep the computer Cover OPEN and i can point a normal small fan (the one in my night table)  towards the open case which can throw some fresh air to all the interior...If you think that would help...

Here you can see an image of the same GPU that i have:

Hmm, it probably wont be ok, but you an get a case fan, connect it to the power supply and attach it to the GPU (remove the original fan first). A loose mount with zip ties will be ok.

I wouldn't recommend that. Although there are many passively cooled cards available, thos usually have the heatsink specially desiged for that, while actively cooled cards have the heatsink dimensions smaller.

I wouldn't do it.  You are going to overheat your system very quickly and cause damage.  My suggestion is to replace fan.

Even keeping your case open and blowing a fan directly into the case won't draw enough heat off of the chip on the card.  It needs a proper heatsink with attached fan.

You can get another video card on eBay real cheap:

And here is an eBay link to a fan for under $5.

Do it right the first time and you won't be sorry later.

"... I will not do any work on it, i just need it to be on to be able to access to files during the day, "   ==>  Yes, it's fine to do that.    As long as you're not doing anything that uses the 3D acceleration features of the card, it's not going to be using more than a very tiny % of the GPU's capabilities ... and won't be using anywhere near the power it would use otherwise.

You really don't even need to blow additional air on it ... but it certainly won't hurt to do so.

Thank you guys.

Scottcha, thanks for the links, i already knew about those, those where recommended to me in a previous question. Nonetheless thanks.

I will buy a new card from ebay or amazon in the next 3 days, but it will take 1 or 2 weeks to be delivered because i do not live in USA... That is why i need to be able to turn on this computer with the existing card.

I have an idea, a temporary quick solution...and is that i am going to take the fan to the local PC repair shop and ask them to weld back the cables. I hope is possible, and probably inexpensive...

If i can not fix the fan, i will also buy the replacement fan from ebay just to have this card as a backup.

It should be a faily easy solder job.  I wouldn't charge very much to do it so hopefully your shop won't either.

Gary CaseRetiredCommented:
Ditto ... especially if it's a shop you've used before, they may do this complimentary.

==>  But as I noted, you really don't even need to bother.    If you only use the system to access files, it will work just fine WITHOUT the fan.

Ok so i took it to the local shop and they rewelded both cables and charged me nothing... I guess he tought i was "cute" haha, i am not!!  I bought something at the shop so maybe because of that.

Anyways, i came back and connected it to the GPU and then the GPU to MOBO, i turned the PC ON, and now the fan does not work... Is strange because just before i broke the cables, it was working, it was making a sound but it worked...

 When i first took it out and cleaned it, i noticed it was kind of hard to move the fan with my fingers (well not that hard, but you know what i mean...) but then after i applied some oil (WD-40) to the bearings, they moved very smooth. So that helped. My guess is that it got damaged while welding... Or perhaps they welded the cables incorrectly, meaning the red cable where the black goes and vice versa, altough the tech guy told me that the order of the cables didnt matter....

Regardless of that the Computer is now working OK, i used "PC Wizard 2012" and it showed that the GPU was at 103º CELSIUS and the computer was idle... It seemed strange and I then tried different monitoring software but none showed GPU temperatures (GPU-Z, CPUID MONITOR, SPEEDFAN...

Now i have the computer case open and i  put a very small Home fan blowing towards the GPU, and the temperatures on PCWIZARDS 2012 came down to 71.9º CELSIUS. It has been ON for all the night and that temperature is stable.

NOTE: Next week i am buying a replacement Card. I will get the replacement Fan for this to have this one as a backup, and a new GPU with a significant upgrade but cheap since it is not my main PC.

I'd say the fan is just broken.  Even if they reversed the wires, the most that would happen would be that the fan would run in opposite direction as this is DC current.

That's still a pretty high temp.  I'd still advise against running it at all but if you need to, you need to.

Hopefully everything will hold together until your new card arrives.

you can test the fan on another board - or connect 12V DC to it to test
you can also measure it's resistance; low but not zero

you can  buy the replacement fan on e)bay if this one's bad  -  Never
 run without out running cpu fan !

it can be the motherboard has a problem, or the connector is bad, if the fan is ok

He's not running without a CPU fan...he's running without a GPU fan which I have advised against.

Ok, thanks for your last input and for all your advice.

As a conclusion:
- I have the PC on because i am on urgent need to take out some files from it. As soon as i finish i will turn it off and try to use it the least possible. In the other hand, i have searched a bit on google and it says that up to 90 Celsius for a GPU is fine, but that it should not get beyond 125Celsius... Either way i will stay safe and turn it off as soon as i can.

- I will buy the replacement Fan so i have this card as a backup, and also a new upgraded card.

- Regarding Nobus last comment, i dont know how to do most of those kinds of tests, i am sorry i do not have those skills, but i will try the card on another board and see what happens.

So, thanks very much again for all your help. Is interesting how many small things can happen on a computer, and one learns a little bit more each time.

And if I'm not mistaken, it would probably run at 5V, not 12V.

It has been ON for all the night and that temperature is stable. " ==>  GPU's tend to run a good bit hotter than CPU's.    That temperature is a bit high, but it's well below the thermal threshold for modern GPU's.

As I noted before, as long as you provide a bit of circulating air, and do NOT do anything that requires 3D acceleration, you can use this as is to access your files with no problem.

By the way, polarity DOES matter with a DC connection ... I wouldn't be surprised if the red/black wires are reversed in the connection to your fan.    But it's hard to complain too much, since they didn't charge you to do it :-)

Thanks Gary, you are right, perhaps is a matter of just changing the cable order. Perhaps i mysefl can buy a simple welding tool for less than $10 bucks at the hardware store and try this myself?

I guess i dont have anything to loose, and i can learn a new skill... I have seen this before, i think is a simple task even for someone that has not tried it before...

you can find soldering tutorials on the net : http://www.aaroncake.net/electronics/solder.htm

i also suggest NOT to buy a 10$ iron, but better one of o good brand , eg Weller

rindiCommented:
Usually you don't even need to do any soldering. just check if you can remove the connection pins from the plastic plug where it plugs to the card, and then inserting them back in reversed order.

Also, it wouldn't be a "welding tool" you'd need, but rather a soldering iron (along with solder of course).
