I have air flow fans can i exchange them by static pressure fans ?I don't know exactly what you mean... But, a higher static pressure is to allow the fan to overcome the resistances of a heat sink, wire mess, dust filter etc. As long as the static pressure of the fan is higher than the resistance, you will have air flow, and the higher the difference, the higher the flow.
I dislike my fans so i decided to buy LL Fans and exchange themit's not recommended to use SF fans as case fans. they are more for heatsinks, radiators and other uses where the air has to "squeeze" into places.
stick with what you have for case fans, it'll make for better flow inside the case.
i want a good air flow fans with beautiful rgb to place it at frontnot a biggie. i usually replace stock fans myself right away. but stick with high air flow versions for the case. the idea is to keep the air flowing from front to back and a static fan won't move enough air far enough to be much help.
imagine a big shop fan that only blew air about 1 ft in front of it vs one that you can feel 30 ft away. that's the difference between static pressure and air flow fans!! the case wants that air moving as far as possible while the heatsink only wants it moving very close by
Yes i will buy 4 fans.(3 pack and single pack)The difference between Air Flow and Static Pressure fan designs is in how much air FLOW the fan can deliver at different backpressures (resistance to air flow). In GENERAL, an Air Flow design will deliver more air flow (and hence more cooling capacity) when faced with a LOW backpressure such as most case vent fans "see". But for specific fan models, look at their specs. Most fans show specs for Air Flow and Static Pressure. In your case, look mainly at the Air Flow ratings, and see whether the fans you are considering can deliver flow as well as others that are specifically designed for good air flow at low backpressure. If your fans have good air flow, then whether they are called Static Pressure or Air Flow designs does NOT matter.
FYI, here's how I understand those fan specs. The Air Flow rating is the maximum air flow one fan can deliver against virtually NO backpressure. But flow decreases as backpressure is increased, and at some point the backpressure (air flow resistance downstream from the fan) gets so hogh that actual air flow becomes effectively zero. So if you sketch out a rough graph of air flow versus backpressure you get a very approximately straight line between the limiting conditions: max airflow at zero backpressure, and zero airflow at the max static pressure rating. You can do this on the same graph for specs from several fans, and see which gives you the most airflow for the backpressure you expect to experience in your application.
Note that the LL120 fans have RGB lighting units built into the fan frames, and require some power and control connections for those parts separately from the fan motor connections. Corsair uses some fan RGB connectors that are different from those used by many others. But if you buy a 3-pack of LL120 fans that INCLUDES two boxes (an RGB Hub and a Lighting Node Pro control box) plus a couple of cables, you can connect those up and use Corsair's free iCue software utility to control the lighting displays.
Ok where should i place them in ? the problem is my case doesn’t support top fans just front and rearWhat about 2 140s and 2 120s?
CM MasterBox Lite 5 RGBActually, the two of each size works well. Corsair sells the 140 mm fan size as a TWO-pack including their RGB Hub and Lighting Node Pro. Then two single 120 mm fans added does the whole job. The questions to be answered are whether or not the case can allow a pair of 140mm fans in the front, and where to place two 120mm exhaust fans. OP, tell us the maker and exact model number of the CASE you have so we can advise on that.
FYI, the reason for this two-size idea is that it is best to have slightly more intake air flow than exhaust, so that there is a small positive pressure inside the case that causes minor air leaks to flow OUT through case cracks, thus preventing unfiltered air intake that carries dust in. Plus, the INTAKE fans should have dust filters on them that provide a SMALL air flow resistance so that the intake fans actually deliver less that their max air flow. The 140 mm LL120's are spec'd at 51 CFM max, whereas the 120 mm models are 43 CFM, so that's a good balance.

Y i was thinking of doing that 3 intake fans at front. and 1 exhaust at rearfront for intake and back for exhaust then. keeps the air flowing in a nice flow across all parts and then out the back for max cooling efficiency

Yes i can place two 140m fans at front or three 120m fansYes, that's ideal. As I said, questions to be answered are:
1. Can you mount those fans that way? Is there space for 2 140 mm fans at the front.
2. You indicated, I thought, there is only one space at the rear for a 120 mm fan. Where do you mount the second exhaust fan?
