Deepcool FH-10 with 3 pin fans

Hi basically the company i ordered from sent me some mislabeled fans as PWM so i ordered them and guess what? 3 PIN!!!

Problem is, it was an international order and it was a massive pain in the arse so i now have the deepcool fh-10 and 9 x 3 pin fans. Will i be able to control the speed of these fans at all?

Sorry, not with what you have. It appears from the Deepcool web page that this is a "normal" 4-pin fan Hub. That means that it MUST have a PWM signal supplied from your mobo's fan header (probably OK for you) AND it can control the speed of 4-pin fans ONLY. Although the description says it is suitable for 3-pin fans, too, what that really comes down to is that any 3-pin fan plugged into it WILL work because it runs full speed and gives you lots of cooling. BUT you can NOT control the SPEED of any 3-pin fan with this Hub.

For what you now have, you need to buy a different and particular Fan Hub. Get the Phanteks PWM Hub, example...

plus at least one 3-pin fan SPLITTER like this

The Phanteks PWM Hub is different from most. It still requires the PWM signal from a mobo 4-pin fan header operating in PWM Mode, but it "converts" the control system so that all of its output ports are 3-pin type using the older Voltage Control Mode. This is the only way to control the speed of 3-pin fans. (As a side note not really needed for you, OP, you can connect 4-pin fans to this Hub also, since 4-pin fans CAN work with input signals from a 3-pin fan system.) Like all fan Hubs, this one has a cable that must plug into a SATA power output connector from the PSU for power to the fans, and one cable that must plug into a mobo 4-pin fan header that is using PWM Mode to control its fans.

This Hub has six output ports, and the specs say it can handle up to 11 fans, max 2 fans per port using Splitters, except that they recommend only ONE fan connected to the white Port #1. To help with that it comes with two Splitters, so that gets you to 8 fans. Buying one more Splitter will allow you the nine fans you have.

Just a note about where to connect. Most mobos now can adapt to controlling either a 3-pin or a 4-pin fan on the CPU_FAN header, but this flexibility is not always available on the CHA_FAN or SYS_FAN headers for case ventilation fans. For that reason, the Hub instructions suggest you plug the Hub into the CPU_FAN header, and then connect the real CPU cooler system to the Hub's white Port #1, since it is the only port that will relay its fan's speed back to the mobo header. HOWEVER, IF your mobo's CHA_FAN or SYS_FAN header(s) does have the flexibility to use real PWM Mode to control its fans, and the fans plugged into the Hub all are for case ventilation, then you can connect this Hub to one of those headers and ensure it is configured to use PWM Mode. Then you plug only your real CPU cooler system into the CPU_FAN header. In this way you can ensure that control of the CPU cooling system will be done by the temperature sensor inside the CPU chip, while control of your case fans will be done by the separate temperature sensor on the motherboard. If you are not sure of your mobo's CHA_FAN or SYS_FAN headers' capabilities on this, post back here the maker and exact model number so we can advise.
