Hi all, this is my first post on the forum. I finally took the plunge and upgraded to a 1.2GHz T-bird with Abit KT7A mb. It's fast and I LIKE IT! But man does this sucker run hot. Previously, I had a Celeron 533 OC'd at 800 running on an Abit BH6 using a nice hs/fan combo from 3dfxcool. Heat was never an issue. Now, I've got so much heat being generated that even the outside of the case is hot.

My case is really not cooled very well. It has only one fan - the power supply fan drawing air out of the case. Now, the first thing I want to do is put a fan on the lower front of the case to draw air in. That way I'll have air being sucked into the front and the power supply blowing hot air out the back. But it's clear even that will not be enough during peak activity (like when I play a flightsim).

I love the cooling setup Dell uses for their Optiplexes. I have a bunch of these on my LAN at work and they are wonderfully cool at all times. Most of the credit goes to the clever plastic duct/shroud that Dell mounts atop the CPU, which leads to a case fan that pulls air out. Most of you guys are no doubt very familiar with the setup they use. As the CPU fan pulls the heat off the CPU's heatsink, the fan at the other end sucks that hot air through the duct and right out of the case, without letting that heat spread out inside the case. It's the most efficient cooling system I've seen yet. But it's proprietary - only mounts in the Dell cases.

It is such an elegant solution, effective yet cheap and quiet. I'd love to get one of these CPU cooling shrouds but I haven't seen any designed for a standard ATX layout. Does anybody know where I can find one?

Boxman,
My Fong Kai FK-320 case came with the shroud that you are talking about. Look on their websie www.fkusa.com for more details. I bought it for my new system from directron.com, maybe they can order the shroud for you. The shroud comes in two pieces, one piece you screw the fan into and the other piece, the actual shroud, hooks onto it. The retaining plugs are not made very well as I have already changed my fan once and managed to break them off. But it seems to do a good job of not keeping the warm air in the case.

Gateway rigs also have the shrouds. The only prob is the PSU fan is weak. I need to slap a bigger fan on it.

Just mount a large fan on the side of the case above the HSF. I bet it works better than a duct from somewhere else.

Hey earthdick (great nick btw) thanks a lot - I checked out Fong Kai's different cases and I like the FK-320 also. I may end up just getting one of these.

The Dell part number for the shroud is 300MX for the GX110, 0462P for the GX300. Do you know which one will fit best? If it is a different model than these, post it here and I will look it up for you and post the part number. Just call their spare parts sales (800-372-3355) and see if you can order one. The shipping will probably kill you though.

yeah, just make your own shroud thing. Will be cheaper and work just as well, You can use anything for it too.

I've been futzing with making shrouds and ducts using file folder material. It's stiff enough to work with, and very easy to cut.

Paper won't catch on fire till it's over 400F. Your CPU will go poof before that. :)

Boxman,

Here is a link that i think might prove useful. i have cut a Duct into the side of my case and have the HSF pulling in Cool air from the outside to cool the Proc......made a huge difference for me. The article spells it all out very well. All you will really need is Corrugated Card Board, Duct tape and a Dremel or Jig Saw to cut the case. I have also Ducted the Front Intake Fans and "directed" them towards the Mobo and Video Card. Again.....big difference. Hope this helps!
