I cut a blow hole in the side of my Tsunami Case last night...

My graphics cards have been getting really hot in my sli rig. So, a week or so ago, I installed the FB123 arm that has a fan and aimed the fan right on the graphics cards.

So, I thought if I could get the fan right above the graphics cards AND have it blow in fresh air that it would work better. I took a 3 1/2 inch hole saw and cut a hole in the side case window (90mm hole) - turned out that the place where I wanted the hole contained both the plexiglass and the metal. I went for it (nervous as can be) with a hole saw and cordless drill and managed to cut a pretty neat hole. I clamped the side window to a piece of plywood for support during the process.

So, after all that, what are the results? Well, believe it or not, NONE! I was expecting at least a couple degrees drop in the cards over the FB123 method and got no drop at all. Oh well, at least I didn't screw things up.

Forgot to mention that I attached a 92 mm fan to the blow hole and aimed it over the cards so that air was blowing into the case and over the cards....

pics? tools?

i'd like to do some cutting myself.

Yes, I'll try reversing the fan and see what happens.

No pics yet, I'll try to post some soon. The only tools I used was a cordless drill, a 3 1/2 inch hole saw (you can buy them at Lowers or Home Depot), 2 clamps to clamp the side case to a piece of plywood.

One thing to note. If you press down to hard on the drill, it will bind up. The trick to it (at least for me) was to let the weight of the drill do the work - takes a little longer but kept it from binding up. I also practiced a couple of times on a scrap piece of plexiglass first to get the hang of it.

Oh unlucky Davey, What are you using to view your Temperatures? Because when i didn't flash my BIOS before the temperatures were displayed 110% wrong, but after i flashed my BIOS it showed the temperatures correctly.

 

[DaveyTN]

I'm using NVidia tools to view the temps on the graphics cards. I'm using NVidia drivers version 71.89. I have a DFI LanParty SLI-DR mobo. Do I need to flash the bios on the mobo to a different version?
