Blow hole in door, do any good?

I just bought a Cheiftec case but it has no hole in the door. Is it good to have the extra fan blowing on the GPU? I mostly want it for looks as I'm not going to be clocking my Ti200 to out ragious speeds.

Is it easy to do? Directron.com will cut a hole for me for $20 and install a fan so I wont have to worry about wrecking anything. Anyone ever had them do work for them.

Could I do it with out ruining my case?

Also, where can I get some fan grills with a logo or something, not just a plain jane grill?
 
Assuming your chieftech is like the antec 8xx or 10xx, and you fill up all 4 fan slots, a side blowing fan may have little or no effect, but theoretically, having cool air blowing over your pci slots may help...

You could do it yourself w/o ruining your case if you had a dremmel or equivalant

color grills

custom grills
 
on you question of whether it helps... i added a 120mm blowhole (exhaust) in the side, and had all other case fans doing intake, and my temps dropped nearly 10 F...
 
So What size hole saw for a 120 fan? hmmmm..

So did you drill out the fan buy guessing where the AGP slot was or did you measure it out?

I just might gice it a try and save me a few bucks.. Would hate to ruin a new case though.🙁
 
The more fans the better! A 120mm in my bros case dropped it by around 10 degrees, i put a 92mm in mine and it went down around 5....then i added a delta and well now i'm running around 22C normal operation, down from 55C 😀

www.2cooltek.com has some pretty good information, browse the case moding section, shows how to go about some of this stuff, good luck!
 
Thrlskr,
It is certainly not hard to do this yourself if you are careful. I usually use some masking tape to outline the hole and cut it with a dremel tool. No big deal and yes, you would see a benifit from it. However you must measure it out and put it in the right place. Don't just "give it a try".
 
i dont have the case anymore, but i have an old case that had a 120mm fan on the window and the hole in it is 11cm diameter. you certainly want to measure and mark out where you want the hole, as well as carefully mark where the small holes for the screws are going to go. if you mess up or dont like it you can always get a window kit with a precut fan hole 🙂
 
Thanks for the tips guys. I ordered a grill,Red bio hazard ,and 120mm sunon fan as well as a red mesh filter. It looks like you can also use a skill saw to cut the hole. One of the site showed a guy doing some case mods with a skill saw so I might try that. And like Jordo said, i can always get a window if it goes to hell. 😉
 
Fan grills make great templates for both the fan hole and the screw holes. You'll probably chew through a few cutting wheels if you get a dremel. Make sure you don't use a cordless dremel for this! 🙂

Actually that isn't really true. I have done this mod and there was a significant drop in my cpu temps and motherboard temps even with all four fan mounts being used. I experienced a temp reduction of 4c cpu and 3c motherboard temp readings. Only thing i did differently was use a 92mm fan and position it higher in the door over the cpu northbridge area of the board.
 
I'm just doing it for the "cool" effect but if it runs cooler then that's a bonus. I already have 4 fans so i'm not to terriblely worried about the temps. I wish I had the guts to cut a hole in my addronics case. A nice 92mm would fit great in the top.
 
One more thing. How do you tell if your PS is big enough? My case came with a 300W. My addtronics is only a 300W and it runs 5 fans.. 4 80s and a 60 with out a hitch and since I'm just moving all my HW to my new case a 300W should work fine since I'm still going to have 5 fans but instead of the 60 I'll have a 120 with 4 80s.
 


<< How do you tell if your PS is big enough >>

Your system won't boot. 😉 Actually it will depend upon what other components and load is on the PS. If you are running a T-Bird, a couple of HDD's', a CD and CDR, etc then you may want to get a better PS.
 
I have a PIII 700@933, 2 WD HDD, CD, 5 case fans.. Gorb on CPU and Sorb on Ti200 and small coffee pot.

LOL!! Damned near fell out of my chair! 😀 Actually, since you are using a PIII your power demand is a bit lower, however I'd still like to have a 350 or better with all that. Hey, if it runs then who cares, right?
 
That's the way I see it too. I was telling my wife about my "mod" I was going to try so I showed here some pictures for some different sites.. She wanted to know why I wasn't putting a window kit in it.. 🙂 And here I was worried she would think the fan was a dumb idea.🙂
 
I use a 4 1/2" hole saw for the 120's and a 3/16" or 13/64" drill bit for the holes for the screws for the fans. If you going to use a hole saw to cut the hole, I found the best way is to lightly clamp the panel to a scrap piece of 2x6 or 2x8, this way the pilot drill bit on the hole saw can help stabilize and get less wandering on the the cut. I then use a deburing tool to debur the smaller holes and a file to debur the 4 1/2 hole.
I found a place that sells the blacker and decker 4 1/2 " hole saw with built in arbor for $16.40 plus .70 for the pilot drill, most place are $35-holes saws get real expensive once you go above 4"
