Fan Health

[Guest]

I'm relatively new to overclocking and modding and all that jazz, and I'm a college student (read: broke) so I'd like to be rather careful with my equipment. So I'd thought I'd ask before I starting hacking my case. I've got a Dr.Thermal EXTREME strapped to a Athlon XP 1700+ on a KR7A. The EXTREME part of the Dr.Thermal (if you haven't seen it before, you can only buy them at crazypc.com - good cooler!) is a 68 cfm Delta 80mm. My temps are not too bad, but my room gets pretty warm out here in west Texas. So I need the coolest air possible running over my CPU - so I was thinking of putting the fan from the orignal Dr.Thermal (70mm 38 cfm) directly over the CPU fan blowing onto it. I know I talk to much, so here's my question: The extra airflow will make the delta spin faster, yes? Will that put extra strain on the motor? I have seen this done quite a bit - but I used to have a little desk fan blowing into my case with the side off and I had two fans die on me and I wonder if it was because of that... maybe just extra dust though? OK, I'll stop rambling now. Thanks for any help! God bless.

You can put a fan over it, you can also have an intake and an exhaust at each end of the base unit (intake - front bottom, exhaust - rear top) for moving air through the case.

This prevents a build-up of hot air in the entire case. This allows the chipset, PCI cards, drives etc from contributing to the overall heat.

Thanks! I was just worried about over-spinning the Delta. I've got a 92mm panaflo up front and two ex-cpu fans (60mm) as a blowhole top-center and one just beside the cpu, so my case cooling is ok... I don't have alot of room for anything else so my only remaining choices are a side fan or a bigger blow-hole fan (though I don't have enough room for really anything bigger than an 80!) Or I guess I could get a new case! Anyway... just so long as it's not gonna burn anything out I think this side-fan is my best bet.

If you can, you might want to consider modifying the 60mm holes to 80mm. This naturally increases overall airflow through the case.

Blasting the CPU with air isn't always the best idea. Just having a decent constant airflow over it, refreshing the air should do.

Try to make sure the amount of intake is the same as the amount of exhaust for best results.

I thought about 80's, but the rear fan doesn't have room for it and I had two ex-CPU fans (so they move a decent amount of air for a little guy, 27 and 26 cfm) so I just used the other 60 for the blowhole - I don't have alot of room up top either. Of course, the PSU has an 80 blowing out as well. So I had a more air going out than coming in (My 92 up front pushes about 56 cfm) But I went ahead and cut the hole and put the 70 in - it made the delta run about 100 rpm over, and it dropped the CPU temp by 2-4F. I should have relatively balanced airflow now - probably a bit more in than out really. Thanks for the thoughts!
