Search with Google, like seriously, it's clearly mentioned in the 'specs' tab of the product pages. You dont even need to download any users manual.

 

You can make these two share a fan header no problem, 0.75A (+-10%) in total

The corsair fan draws 0.3A

The Bitfenix fan draws 045A (+-10%)

 

Also the corsair one has a higher RPM, and so I suggest that one personally, and all the currents are nominal values, meaning the actual current for both might spike above them, depending, e.g. when you first turn it on it might draw an amp to start spinning. General rule though, all fan headers support all fans, if the fan can draw 2A, but only can get 1A, then it will only get 1A, cause that's all it can be supplied to it.

 

If you want to find this out in the future just google the fan and look at the tech specs.

i found the running ampage but i coundnt find the start up ampage. Also is it true that if the fan takes more than 1 amp from the header it will burn it out(saw on tom's hardware)

it won't burn out, current is drawn, and there is a maximum current able to be drawn due to internal resistance etc. (that's why when you short a 9V DC battery you get a couple amps not infinite (which is what would happen if you have no internal resistance)) meaning that the fan header won't burn out. You just being overly cautious here, Also the fan header will be 1A nominal (average), but will also have a higher burst current (the max current it can be drawn over a very short time) meaning it is completely safe to do it with any of these fans

Amp listed is max and that's all you need to know.
