T5400 Fan / Graphics Card Temps

Question

My new T5400 showed up and I've made the necessary changes to the system for my video editing company which includes the upgrade of the GPU to an MSI Radeon 3870X2 and a Matrox RT.X2 Realtime editing card.   The issue that I'm having is the GPU and the editing card sit next to each other and since this is a tower the heat from the 3870 is basically cooking the Matrox RT.X2 both cards are showing temps at or about70c.   There is a fan on the front of the case which is set to blow out not in so it's pulling hot air out of the box, the other fans in the system are over the memory but it appears that all are setup to be acousitcally pleasing.    I am wondering if there is a software program that will allow me access to the fan settings not currently in the bios, I really need to get the case fan moving more air, noise is not an issue. I know that if I boot the system with the case open, the ventilation warning comes up and then I get all the fans at full power, but then I have an issue with running an open case.    One more thing I'm curious about is if there a fan kit available from Dell to add another fan on the back of the case connected to HD Fan port which currently shows open on the Mobo.   Miguel

I wouldn't install a fan utiltity in that system.  You have a great workstation and you are taking a risk on missing it up.  If anything how about installing a PCI fan inside the system to blow on the cards?  They have some that have adjustable speed and work really well.

Thanks for your reply, a PCI fan is out becuase I have something in every slot, so no room left, but in the last part of my message I was wondering if there is a fan kit to place in the 2 fan openings above and behind the memory, some more air there might be the solution, I just need to check the parts site to see if there is a kit.

I think you will need to come up with a custom fan.  Good luck finding somthinig.  If you do find one let me know on this form.  Have a great day.

Hey I also have the T5400 and when I put in a second graphics card I found my main one was running hotter then I wanted so I ran to Circuitcity yesterday and grabbed a Antec 80mm fan and put it on the back. It helped lower my graphics card a couple degrees but not much. It mounts easily on the back with the four screwes supply with the fan.

You will might as well try it, it can't hurt and there is room on the back of the T5400 for 2 80mm fans. I wouldn't hook it up though to the hard drive power jack on the motherboard. I would hook it up to the 4 pin power connector comming out of your power supply.

Most of the Antec fans use the 4 pin and allow you to connect another 4 pin to it incase you are currently using it for something. You might as well try it the fan is only $8. It did it and it's helping a little. You can always buy a speed adjuster if you want to slow the fan down.

Hi, I know this is an old post, but I am having a similar issue.

With two quad 5460, two SATA drives, a Perc5i and a 4670 video card, I am getting CPU temps ~44C, RAM ~ 60-70 C, and video ~ 65C !!

I am planning to put two 80mm fans in the back pushing air out, based on my front fan pulling in (original poster reported that his front fan was blowing OUT, not in like mine, not sure what's default).

I haven't opened the case recently, but is there space for a 38mm or only a 25mm deep ? Any specific recommendation for a model with efficient airflow for relatively low noise?

Thanks,

Max
