Corsair Graphite 780T Full Tower ATX PC Case (Black)

It came with 2 front fans (red lights)
I see there are 3 bays on the top i can purchase more fans, im just not sure which ones, as i want them to fit and also match the rest of the case?

The 780T, aside from the included 2x 140mm fans in front (intake) and 1x 140mm fan at rear (exhaust), has room for 4-5 more fans: 2x 120mm at the bottom (intake) and either 2x 140mm or 3x 120mm at top (exhaust).

Typically, the pre-installed case fans (2 intakes and 1 exhaust) will usually suffice for a positive airflow in your tower. Adding/filling-up the remaining fan slots is optional. The advantage of having more fans is the opportunity to either have a faster rate of air exchange/flow (in CFM) at the expense of noise (higher dBA) or have the same rate of airflow at lesser noise by decreasing the speed (in RPM) of the fans.

The stock fans that come with the 780T is the Corsair AF140L. If you want to match the same fans, you can...

The stock fans that come with the 780T is the Corsair AF140L. If you want to match the same fans, you can purchase the AF140 and AF120 Red Led fans here:

120mm: Corsair - Air Series AF120 Red 52.2 CFM 120mm Fan ($13.89 @ OutletPC)

140mm: Corsair - Air Series AF140 Red 66.4 CFM 140mm Fan ($13.19 @ OutletPC)

Note that it is ideal to have positive airflow (where the total CFM intake is higher than the total CFM exhausted).
