Cooling my G400 ( Warning ! - shown with pictures ! )

It was really hard to decide, especially on the backplate ... Superglue was my choice.

Maggi,

No way! - It looks like you used an old "Speaker" mount from another case to stand off the "Big Fan" from the card... Whoa!! Cool.

hehehe ...

that big fan has some sort of cover to protect fingers that are too curious

I used superglue to attach a pentium fan to the g200 heatsink since November and never had any problems. And believe me, it has been running hot
When my g400 arrives (to the end of this month, boohoo ) I will put it in the heatsink too.

And just a question, to you G400 owners: The heatsink seems rather large, is there any way two pentium fans would fit?

Sorry

I just got my G400 this week; haven't finished building my new system yet . The heatsink doesn't seem to big enough for two Pentium fans maybe one and a half but not two. Look in the thread of Hmmm My g400 runs hot...or something like that in this forum they have some good ideas for cooling. Also can anyone recommend a case (full tower,300W) Also how do you use UBB Code?

Superglue? I was thinking maybe something involving the strips from ZipLoc bags. Now that would've been cool...

On another note, I've got a pile of hard drives in my system. 2 ide and 2 uw scsi. I'm having some trouble keeping them cool. Anyone know of a good way to cool hard drives, besides cutting a hole in the front of the case and mounting another fan?

I already have two case fans, plus the power supply fan, all blowing in to the case (the case has vents for that air to exit, positive case pressure is key!).

Room temperature is kept at 21C, but over time, the MB temp gets up to about 35C. I think it's mostly the drives causing it.

Maybe if I do cut that hole, and mount a fan sucking out air across the drives (and seal up the vents) it will make sure the hot drives don't heat up the rest of the case.

I don't know, I need some ideas. What do you guys think?

Actually, negative case pressure is better. The best option is an air flow pattern, though. If you get all the fans in the top/rear of the case blowing exhaust, and a respectable intake fan down in front, that's probably the best way to go.
Other fans:
I have an 80mm slot fan in my uppermost slot, and that really helps. The air coming out of that thing is hotter than what comes out of my power supply.

If your HD's are your biggest heat problem, have you looked into bay fans? They fit into the 5-1/4" bays, and are made with HD cooling in mind.

If you can get you hands on some sunres, that would work well. Except you wouldn't ever be able to remove the fan...

The people who make the "NerdBox" (dual celeron overclocked to madness) swear by positive case pressure. If you're forcing cool air into the case, it guarantees that warmer air is blowing out. If you're trying to set up an air flow through the case, you can't guarantee that cool air will get into all the corners (It'll just pass right through).

Also, if I put an intake fan in the lower front, it will just blow straight out the lower vents. If I put an exhaust fan at the top/rear, it will suck air in the top vents, and send it straight out the back. I had it setup this way originally, and now with all intake fans, the mb temperature is lower by a few degrees.

The point is, you want to swap all inside air with outside air as often as possible. I guess as long as all your fans are doing the same thing (intake or exhaust), you'll be okay. An airflow can leave pockets of unmoving air, which is bad.

I think I will get myself a drive bay fan (or crudely fabricate one out of a standard chassis fan more likely) and have it exhaust. I'll have to seal the vents for this to be effective though. Can you get fans for 3 1/2" drive bays?

Dear Maggi,

That is very impressive how will you get the rainbow runner next to it?

Maggi,

I can't believe you have another place for a fan and you don't even have one there. Look at the 8th picture down(second to last), above the parallel and com port mounts. There is a place for a tiny fan. Maybe there is a reason you are not using this?

Interesting...but Superglue has poor long-term characteristics when exposed to any real heat source. In a few months, you will hear a 'CLONK' as the fan or fans part ways with the card. Suggest you find a mechanical remedy...

[tylau]

It is not much use for huge fans with massive ari blowwing over chips without decent and big enough heat sinks over them, it is just a waste of your p/s energy since air/solid heat transfer is far less efficient than solid/solid heat transfer(which is what a heatsink and the hot chip does). Back to 1st lesson, the use of a heatsink is to increase the surface area for heat transfer between solid/air, so that even if is not as efficient as solid/solid heat transfer, it still much better than a bare chip.

I just returned from a weekend break, and looks like I was promoted. What would be a better way to end a good week..
