do you have to use both fans or is it possible to just use one fan with this?

you can use one fan if you like. You wont get the most out of the cooling, but it will still cool very well. My recommendation would be to replace the fans with one really good SP120 fan. Here is my install video of the process. https://www.youtube.com/watch?v=rrBfVgpGhUc&list=PLvd6GtnBmcZlnf43RFLr16nLSY8dWYXqQ

I would actually use 2 fans. One to push and one to pull. I used these for a Dish Network receiver which runs very hot inside the cabinet. I used one fan to blow air into the box and one fan to pull air out of cabinet. Works great.

There are 2 connectors. You should really get a fan controller or something of the sort. Two fans won't cut it. I have 10 in mine but that is all personal preference.

Return the fan.... only one blade works on mine on cool but I use it mostly for exhaust so I'm not gonna go and return it since both blades work fine on exhaust

Yes you can add two fans on the left side panel, but I don't recommend doing so because adding two fans on the side will obstruct the airflow.

You can plug in 3-pin fans in to this and use it to plug 2 fans (2 3-pins or even 1 3-pin + 1 4-pin) in to one motherboard header. You just wont have variable fan speed because the 4th pin is responsible for modulating it.

These fans aren't PWM controlled, so you would need a separate fan controller. If you would rather have PWM fans they aren't much more in price than non PWM fans, you should be able to find some cheaper than these.

Yes if you buy 1, if you buy 2 you could have 4 fans. Of course the two fans that shared one sleeved will run at the same speed and the Mobo only senses the speed of one if you have 4 pin fans.

I installed a Seidon 240M with dual fans on the top. It was very difficult to keep the fan that came with the case also on the top. If you just want to use the two 120mm water cool fans and remove fan that came with the case you will have no issues at all. I just wanted all 3 and was a bit difficult and needed unique set up.

Well all fans blow air in one direction... It's how you install it. You can install them facing in or out this is a standard with computer case fans.

That is an option, but the cooler works well with the two fans. It is the best cooler I have purchased. This is my forth. Good Luck

The short answer is no. You may be able to get it to work but I'd advise against it. Here's the long answer: I bought two of these fans during construction of our new house and had hoped to run them both off one controller. The electrician who wired the house connected both fans to a "universal" fan controller, the kind that fits inside the wall box like a light switch. One fan would work pretty well but the other fan would only jerk as though it were trying to start but couldn't. The electrician then tried a similar controller that was supposed to control multiple fans. They both worked better but made noise. About this time I dug up the instructions for both the fans and the controllers. The fan instructions specifically say "To reduce the risk of fire or electric shock, do not use this fan with any solid state fan speed control device, or variable speed control". The controller's instructions said "CAUTION: To avoid overheating and possible damage to other equipment, do not use to control receptacles, fluorescent lighting fixtures, or transformer-supplied appliances". We then tried running both fans with one of the supplied transformer type speed controls and that didn't really work either. We finally decided that we don't really mind the "vintage" appearance of the supplied controllers. In fact my wife actually likes the way they look. Because they stand out from the wall we mounted them above the switches controlling those circuits (on/off) so they're just above shoulder height and we're less likely to bump into them as we walk down the hall. The fans are great. We still love them and would buy them again. We'd just skip the headache of trying to avoid using the supplied controllers.

No fan is required, passive cooling is just fine. I run two of these 24/7/365.25 no issues.Make sure you get an adequate power supply.

Yes but they are low to medium at most RPM so you don't really need a fan controller and actually if you plan to use one, you ought to get different fans capable of higher RPM so you have the ability to do both higher airflow if needed and low airflow when you don't.

One fan. Furthermore, any PWM splitter is only going to be seen by your motherboard as one fan as only one of the connectors will be wired with an RPM wire, while all will have GND, +V, and the sense wire to control fan speeds. Any non-PWM(voltage controlled) splitter will only contain RPM on one fan and GND/+V. If you want to see individual fan speeds you will need to use individual ports on your motherboard or fan controller.

Yes, you can add two extra fans on the left side panel. Any size. Make sure you have enough fan controller plugins, if not buy a fan controller card to plug into a PCIe slot.

Yes I don't think two fans will be needed however. They put out a great amount of air and also pressure.
