Stock Vapochill LS. Does changing the fan on the condenser help?

[terente0081]

I was thinking about swaping the stock Panaflo FBA12G12M1A fan on the condenser of my stock Valochill LS unit with a Delta fan. The Delta has 2 times the CFM of the Panaflo (190CFM vs 86CFM).... will that help with temps? By how much?
I have the Deltas in hand, I don't know wether it's worth the swap or not. I will certainly get some increase in sound :) how about temps?

If you're OK with high noise level or in case the unit will be exclusively for benching, not 24/7 usage then i would recommend it. VapoLS has a relatively small or undersized condenser, i have experienced this with modded Mach I., it got me 4-5°C lower evaporator temperature with stronger fan.

Stronger fan for sure will help, moving more CFMs will 90% time mean better cooling.

Re-insualting the thing with thicker stuff also helps a lot, i got an extra -15c on a 2nd hand unit i bought just with new insualtion and the fan uprated.

Then hard mods, cap tube soldering helps a lot if on a quad, re-gas, bigger condenser, removing 7/8'' of cap tube for quad tuning

Thanks for the info. I will make the swap and see what results I get. These Delta's are quite noisy, but they do move lots of air.
One question though.
If I swap the Panaflo fan with the Delta, will the fan controller of the Vapo be able to provide the extra Watts needed by the Delta?
I believe there's some difference in Wattage; Panaflo requires about 5W while the Delta requires 24W.
Will the fan controller hold or will it blow?

Better put the Delta directly to your PSU!

That actually is a very good question, wish I had a valid answer for you though but I'd be wary of straining the powersupply on the VapoLS. The damn boards seemingly die at the slightest whim. If you don't mind the ghetto look, fans in push/pull sandwiching the condenser could help while letting you under-volt the fans but that still leaves you with the issue of powering them. If anything the stock panaflo wired into the controller and an external delta wired into the PC PSU to fire up when the PC comes online.

Be sure to take valid measurements (temperature wise) before swapping the fan. Look in the BIOS temperature aswell and write it down (in case you mobo sensor shows subzero temperature) and then report back! :yepp:

[terente0081]

I will make measurements and report back. I just need to figure if the fan controller will hold the Delta fan.
Is there any way to combine all the fans on the Vapo LS fan controller with a strap and connect the Delta to that? I believe there are 4 fan headers on the board that I am not using.

Check the manual and see if those headers can support the wattage of the new fan. They may be like 5w max and the 190cfm will probably be 10+w

You can use 12-220V relay box & some very old 150W AT PSU. Vapo's controller will give out 12V signal to fan header, which you plug into 12V-220V to start the old AT power supply which would feed the fans.

EDIT: or 12-110V if you live in a country with 110V power network grid.

That is a great ideea. If I only knew where to get a relay box from... I never used one and I wouldn't know where to search. Any ideeas?

If I recall correct they can provide 15 watt. The fan heads that is.
I have spoken to Asetek alot of times :)

So if you use a 2 x 1 fan whire you would have 30 watt.

Yes, but then I need to know if the fan headers support bridging. They may either support it and the scheme works, or, it may not work and get a burnt ChillControl as a result.

On a sidenote, what about swaping the Panaflo M1A (86CFM) with a Scythe Ultra Kaze 3000 fan (133CFM). The Scythe eats about 7.5 Watts so it should work OK directly plugged into the ChillControl.
I don't have a comparison between the two, Static Pressure wise. Any ideeas?
