Fan over sump?
 

Would a fan blowing over a sump in a cabinet be as effective in reducing tank temps as a fan blowing in the hood? We're talking possibly reducing temps in a 120gal by 3-4 degrees? I have a fan in my hood now but it's not doing the job by itself. My canopy setup doesn't allow any additional fans however, so I'm wondering if I should bother buying a cheap house fan and sticking it over my sump instead, or shell out more dollars for a higher powered, thin fan to replace the one I have now in the hood.

Cheers..

I have two 6" clip-on fans from Canadian Tire running over my sump, and if they are not on, my tank temperature rises very quickly. The two 4.5" fans in my hood don't seem to affect water temperature at all, but I think they are useful just for moving evaporating water out of the canopy and so on.

Thanks Quinn! I think I'll go out and get a clip on fan today.


PS. I just spent a weekend in Red Deer for racing (National Autox Champs). Great town! It's amazing how much stuff was packed into the one street we stayed on (forgot the street name already). Those little tiny bugs that land on you in groups of hundreds were a little freaky for us Vancouverites, but it gave the Albertans we were with a good laugh when we ran around screaming :lol:

Without my fan blowing on my sump, the temp gets up to 85 in a couple hours. With the fan blowing on the sump, it stays at a nice 81.5 :)

hth

You were probably downtown where all the bars are? There is a whole strip of them down there. What's autox? Import racing?

How much do those Clip-on fans cost?

Walmart has a desk fan for 6$. I think its 6".

Imports do race, but it's not exactly "import racing". Here's some multimedia on Solo racing (autox or autocross is a form of solo racing). I basically do the stuff in these vids. Autox is the ones with the cones.

I got one from a Dollar store for about $20. It seized up after a year (3-4 months of use). This summer, I bought one from Canadian Tire for about $15. Its a Windmere. The one from Dollar Store was a no-name brand I think.

This is what I use now. Seems pretty decent.

My fans were about $15. They still work after about three months but they are covered in salt creep and are rusting now.

Interesting stuff. Where did they hold the races here? I wouldn't have thought Red Deer had particularly spectacular roads, although there are a lot of crotch rocket and import racers around here (they keep dying).

autox is some cool stuff. Too bad my car is auto - sucks for coming out of the turns...

:)

I have a 10" Honeywell blowing on my sump and without it I'm sure my temps would be ridiculously high.

Troy, what kind of evaporation do you get with that?

Ok we're way off topic here. I am assuming these are standard production cars right. Are they souped up? I have a 92 2dr Jetta I wouldn't mind getting to go a little faster, or at least I'd like to learn how to handle it properly. Any websites relating to this?

Depends a bit on the humidity but around 3 maybe 4 gallons.

Cars have fans too.

We did it at the Westerner Park. They had a huge parking lot there and a 1km course was set up with cones. Anything from bone stock family wagons to custom built race cars attended. There are basically different classes depending on what car u have and what you've done to it to make it faster.

Check out the following sites:

www.vcmc.ca (Vancouver based, although we do have quite a few members from Alberta)

I'm quite involved in it so if you'd like I could hook you up with some Alberta based drivers and they would probably be able to better explain when and where they hold events there.

Here are a few pics of what we were doing. I hope the pics stay up!

Apparently the whole of Alberta was on fire when we got there...

If u guys want more pics i have tons more :)


Back to the fan in the sump :razz:

Is everyone just using little fans or 6"+ sizes? I just wanna get an idea of what to look for tomorrow at Canadian Tire. Don't really want to waste any money on useless fans, but I also don't wanna overdo it!

Thanks!

I find the bigger fan controls the heat very well.

I havent been able to find any fans that would work in my sump :(

I have a windmere rotating fan sitting on a step stool blowing down into my sump thru the stand door. I want something that will sit inside the stand and blow on the sump directly

btw sos - great pics.

I'm so jealous. I even see a pro5 in there... but I bet he is running stick, not auto like me ;)

LM, try setting up some kind of rack and lay the fan across it facing down so it's pointing at the water.

Just in case anyone cares, the 4.5" fan I put in my stand door has been AWESOME for venting humidity. This seems to be helping out my temperature a little bit as well.

That's pretty cool. I'm suprised I've never heard of that type of racing. I really love those old Austin Mini's. As far as I'm concerned, the new ones are crap. Like the second Woodstock, you know. Can't believe someone has a Porsche in there. Must have a lot of money to throw around.

If you were at the Westerner then you're probably talking about just that big new development area at the south end. It's quite something for such a small city. Just about every need satisfied within a few thousand square meters of asphalt and gaudy signage. :razz:

Thanks Troy.

I am going to have to do something like that soon :)
