What issue is there with fans in pull/pull instead of push/push? It really doesn't matter if fans push air into cooler or pull air out of cooler. Performance is near identical. Using F12 will low cooler performance .. F12 is 53cfm; 1300rpm compared to Ph-F140HP_II is 68.1cfm; 1.62mm; H2O 1600rpm. You would be better off using only 1 PH-F140HP_II fan.

Will have to talk with Gigabyte to see if removing the stock fans would void my warranty. For Asus cards it doesn't but it varies by manufacturer. I already sent them a ticked complaining about the loud grinding noise at fan ramp up from 0%. I pushed the cables behind the fans inside but it's still present. Seems like the issue was fixed by a BIOS update for 1070/1080 cards by longer ramp up time.

I have no particular issue with pull/pull. It's just a bit odd for me and looks strange. I did not intend to use only 1 PH fan, I'd rather have cooling performance. Did not think that a lower CFM fan in the front would make the performance worse. I was thinking that it would help to push the air through the fins for the middle fan. Without the F12 the air would be going through much slower and I thought the extra fan would push the air through the fins faster then by being sucked in. But I was also thinking that maybe the F12 would just be in the way of the air that otherwise would be going through the fins faster.

Maybe worth testing but probably I'd end up your way smile.gif

If Gigabyte will allow owner to remove & replace cooler to apply TIM or to use waterblock it will be okay to remove fan shroud and fans.

Push or pull is a fan & fin pack make no real difference. almost all fans work in the same pulling or pushing because fans function because of the pressure differential between their intake and exhaust sides. When they are mounted onto a fin pack the pressure differential is between fan intake and fin pack exhaust .. or .. fin pack intake and fan exhaust. Either way the pressure differential is the same.

Waiting for Gigabyte for my answer. Some guys on other forums say that most of the times you can take off the coolers and if something is wrong with your card you just put them back on and RMA it.

I'm pretty much ready to buy the Phanteks cooler. Now I just have to time the purchase right as I'll be away starting from the end of the week. I don't know what kind of fans are on the cooler. On their website it's a 7 blade which should be the MP (68 CFM) version or the HP II but anywhere else I see 9 blades which is the HP (up to 89 CFM) version.

Do you think the 2 Fractal Design Dynamic X2 GP-12 fans in the front of the case with their 52 CFM (minus the dust filter) would provide enough air for the cooler fans when the GPU fans are also needing air? If not enough what fans would you recommend (I know you like TY 14x)? I was thinking about getting 1-2 of PH-F140HP as they provide the same air pressure and CFM at lower noise then the MP version. SPCR said nice things about it and I don't have anything against it's sound signature.

All new PH-TC14PE have new PH-F140HP_II fans, so unless your supplier is sell very old stock that is what it should come with.

I don't know if your GP=12 fans will supply enough air or not. Best way to find out is try them and monitor cooler intake air temps .. and see how much warmer cooler intake air temps are under heavy load. The 68cfm vs 89cfm is free airflow, no restriction. The PH-F140HP_II should have higher static pressure, but specs show them the same. I have to wonder how they got their specifications. CT testing shows HP_II / MP style impeller being better performance and quieter. I got the same with my use / testing

Thank you for the info! I do wonder how do you still have patience for me...

I do like quiet fans so might go with MP / HP II. Hopefully my temps will be low enough that the CPU fans won't have to run on 100%. That way they will be more silent and the GP-12 fans will provide enough airflow.
