Help with fan/controller setup please.

post #1 of 6
Thread Starter 
Trying to keep things cool and not fry anything in the process.

Have a Lian Li PC-65B which doesn’t have the best air flow.

2x80mm in the bottom for intake - 2x80mm, one below PSU in the back and one in the top for exhaust.

Most likely going to cut a 2nd 80mm hole below the one in the back for more exhaust and maybe buy a LL HD bay that comes in either 80mm or 120mm for another intake. Which would be blowing straight at the HSF.

Using the stock cooler atm for my E6420, but planning to get the Ultima-90I from Thermalright that comes with a 92mm (can use 120mm) fan. Supposed to be out by the end of May or June from what I can find out. Seems to have the performance of the larger 120’s (Tuniq/Ultra).

So in the end I will have 7 fans.

I bought a Vantec 205 witch has 4x18watt max channels. ~$20

http://www.newegg.com/Product/Produc...82E16813999504

Then found the Lian Li TR-3B, but can’t find any specs, besides it having 3 fan channels. ~$20-30

http://www.lian-li.com/product/produ...ndex=46&type=b

Can either of these maintain 6-7 fans? Or would it be an overload?

The Vantec is just knobs, but the LL has a display, so I’m thinking about returning the Vantec for it.

If they would support the fans, would it be wise to have 2x80 on 1 channel, 92 on another, and 3x80 on the 3rd? Leaving the 120 by itself? Or if I had the Vantec, it would go on 4th channel.

Also is it best to have the HFS controlled by me or plug it into the MB and let it decide? I have a Asus PN32-E Plus.

No idea how much controllers can really handle on a channel. Does 18 watts, really mean 18? Or is that in a perfect situation?

If these 2 won’t support my plans, any suggestions for a controller that does?

Thanks for any help.

Im also interested in this question . . how many fans can run on one control? . . . IMO i wouldnt use the HSF on a controller though . . plus many mobo's will send an error or wont let you boot if no HSF is detected. . . play it safe and let the mobo decide

Well, the # of fans goes with the # of knobs.

The Lian-Li says it can detect up to 3 fans, meaning it can control up to 3 fans.

The Vantec (I have a similar model) can control up to 4 fans (easy to tell w/ the 4 knobs)

You can hook up to 4 fans on Vantec, if you'd like then download SpeedFan (a free program. Google it. ) to control the fans that are directly connected to the motherboard.

My heatsink fan is connected to the motherboard, and I am able to control it with SpeedFan.

The only problem is that some fans w/ heatsensors are not able to be controlled with fan controller or the program.

i.e. I have 4 fans w/ heatsensors, and their speed varies via the heatsensors. (speeds up/down depending on the temp)

I have my side panel open, though.. so they usually don't run loudly.

Use a Sunbeam Rheobus. It's cheap, looks good, comes in black and white, has good build quality, and can support up to 20w per channel. Say a typical fan uses 5w, that's 4 fans a channel. 5w (I think) is high-balling it, unless we're talking about Vantec Tornados.

And no, you can plug in more fans than just the number of knobs. Think of it like a molex power connector. As long as you have a Y wire (like a molex fan connection) you can use many different fans. Your limit is the number of watts a channel provides. The Sunbeam Rheobus provides a previously unheard of 20w a channel (four channels).

You can splice fans together to one channel. It depends on how much power the channel can dissipate. If you put too much load on a channel, it will burn out and the one fan controller is dead. The fans would be fine.
