ok cheers fo the advice and links. just a few questions. do i have to screw the fan in, can't i just stick it in? and i don't have a fron vent, so should i get 2 fans, one to suck air in from the side vent and one to blow it out the back?

Unless the case has some fan cages, then you have to screw them in, the fans will come supplied with screws. Have the rear fan blowing out for sure, for the side fan, it can vary - sometimes they work better blowing in, and sometimes they work better blowing out. The only way to find out is to try bothe ways round and monitor the temps and see which way works best for you.

Well just tried the card once again. When i put it in it was very cold and i managed to play Vietnam for about 10 min before it started to over heat so it defiantly is that. Also got Everest and it says my CPU is at about 35-40 degrees C, is that fine?
i have found the rear exhaust mountings and it has room for 2, 3.5inch fans and the case also has a side vent for another 3.5inch fan. Unfortunately it doesn’t have a front opening. Should i get 3 or is that a bit extreme? i suppose 2 should do the job.
Now i just have to decide whether to get the fans and see if the card works, if not send it back or get a replacement card and the fans at the same time?

Those a re good CPU temps...nothing wrong there. As far as those fans go, two 80mm rear exhaust fans might be all you need to draw cool air into the case through the front grill and exhaust it. I would try that first, then add a side vent fan later if the temps do not behave. Look at the side of the fans for arrows that indicate spin direction and air flow. Make sure the airflow is going OUT of the case when you mount those fans.

Looking at Train's diagram above, if it isn't available to put a front intake fan on the front panel, then you might consider sometime installing a fan 'blowhole" on the side panel in that lower front corner...that would still draw some cool air into the case...might add a short angled duct to direct the air towards the motherboard. Would make for an interesting project.

well I’ll look into it.
what connections do the fans have power wise? do they just plug into the 4 pin PSU ones ore will i need some kind of adapter?

**bistro** · May 25th, 2005, 09:31 AM

You can get 3-pin mini-plugs or 4-pin Molex plugs with those fans. The 3-pin variety are for plugging into the motherboard fan connectors (which I generally avoid doing) or into a fan bus controller (such as pictured here). The 4-pin Molex variety are convenient because you use them with your normal power supply cables. You might need to get a Y-splitter/extension cable if the cable length is too short.

3-pin 80mm fan
4-pin Molex 80mm fan
Y-splitter used to connect two 4-pin Molex fans to one power cable plug (or to extend the length of one cable and you just "cap" the extra plug)

cheers for all the advice once again. i got a couple of 4pin fans and a Y splitter cable. lets just hope it works.

Well just to keep you guess informed the fans have arrived today and all is good. Bought 2, 3000rpm fans and they seem to be doing the job. Although if you get to close to my computer the fans suck you in. lol. So cheers for all the help, and wow are my graphics improved, from low to high

.

**bistro** · May 26th, 2005, 12:04 PM

3,000rpm? Whoa!

Hope you can endure the noise level. Anyway...how are the temps?

**judge john** · May 26th, 2005, 01:57 PM

Temps seem to be fine but i can't get a temp for the card and the CPU, memory etc all just a bit lower than before. There not too loud that i can't put up with it but i might take one out and see if the other one manages ok just to keep noise to a minimum.

Bad news again

. The card runs fine when playing games ect so I’m happy with that, but i have found another instance when it does overheat again. I have just got '3dmark' benchmarking program and when i run any of the 3 graphics tests the card again overheats after about 15-20 seconds until it crashes. I mean how many extra fans does this card need to work ffs!

**SuperSparks** · May 28th, 2005, 01:09 PM

I'd say that there is either a fault with your particular graphics card, or it doesn't care for the layout (and hence the airflow) of your particular PC. I think you need to look at getting a better HSF unit for the graphics card, as there is no doubt that this problem is caused by an overheating GPU.

**judge john** · May 28th, 2005, 02:39 PM

well i spent all my money on the card and then the fans so i have no money left for anything else, lol. at least it runs fine with all the games i am currently using and I’ll look it to getting the new fan when it becomes an issue.
