post #1031 of 1039
I think I will get the Phanteks Enthoo Pro M. Planning on placing 2 TY-147a for front intakes. Any suggestions for what rear exhaust fan to use (it supports 120 and 140mm)? Also should I consider adding an exhaust fan up top?

If you have a tower cooler, your exhaust should at the very least have the same airflow rating. I usually like to have the same fans as both rear exhaust and for the CPU cooler and link both their PWM signals. Another option is to have two slower exhausts, one in the rear and another in the rear position of the top panel (behind the CPU cooler and above the VRMs).
You can go for top mounted intakes too. They work well as long as they are mounted at the proper position (right in front of the CPU cooler, but not too far up front or right above). If you do set a top intake, best not to have a top exhaust. Also, top intake fans have an easier time drawing in dust, so make sure you have some extra filters around (and that you like cleaning your case more often tongue.gif). Chances are you don't need an extra intake. Those two front fans you plan on using should be enough.

Planning to use the Noctua NH-D15 which uses 2xNF-A15 140mm. What rear exhaust fan would you recommend if I'm not adding any top fans?

If you don't need two fans on the cooler, then see if one of them fits in the rear panel. If not, there are a few fans that offer similar airflow and pressure, like the PH-140MP. There are other faster fans, but it depends on how loud you want your PC.

I intend to keep both fans on the cooler. The Phanteks Enthoo Pro M comes with the 140mm PH-F140SP for the rear fan. I think that should be sufficient?

The SP is like 70ish CFM with so-so static pressure. Try it first. If you are not pushing heavy overclocks with very high heat loads, the trapped hot air should not be much of a problem. Otherwise you should get a second SP fan as a top exhaust.

Pro M comes with a fan using PH-F140SP like housing and motor with a PH-F140MP like impeller. With 2x TY-147A SQ front intakes I would use it as the exhaust fan .. and remove all unused PCIe back slot covers to increase rear vent area around GPU.

What Malcar said is only partially true. PH-F140SP is a good case fan. In 2 cases that came with PH-F140SP fans I switched to TY-147A SQ fans and tested them to see what the differences were. While there is a little difference in the fan tone, both cases I tested at idle and full load on CPU, on GPU and on bothCPU & GPU. All results were near identical in temps and dB at same rpm.

Also Phanteks changed cases fans from PH-F140SP to a 1200rpm fan (looks like same housing and motor as PH-F140SP) with a PH-F140MP like impeller over a year ago. While Phanteks site for other than Americas does indeed list case fans as PH-F140SP, the PhanteksUSA site removed the PH-F140SP from case specifications and now has no fan model number or fan specifications listed.

If I was building a Pro M with TY-147A SQ front intakes I would block all opening in front panel except where fans are so none of the air front intakes are pushing leaks back in front of intake fans. This forces the intake air to flow through the case .. back around GPU and to CPU, then on back and out of case. And if I wanted to match cooler fans to black & white theme I would use TY-147A fans on cooler. wink.gif

With PCIe slots functioning as additional vent area you probably won't even need an exhaust fan .. and one behind D15 cooler will flow plenty even if it is rated with a little less flow then NF-A15 fans.

I assume you plan to run TY-147A fans so their speed cycles with cooler fans, so they will be supplying cool air to coolers as needed.

Thanks for the detailed info. I've never messed with fan curves before but I'm planning to connect all case fans to the mobo's chassis fan connectors. What do you mean to run "TY-147A fans so their speed cycles with cooler fans" ? Are you suggesting I set the same fan curve for the front intake and cooler fans?
Also same for rear exhaust fan? Should I do this in the BIOS or with software like SpeedFan? Sorry for so many questions, I'm a big noob smile.gif

I mean set setting custom fan curves so case fans are running fast enough to move a little more airflow than cooler fans are using at whatever speed they are running to keep CPU and/or GPU temps where you want them. You might find "Ways to better Cooling" link in my sig of interest. 1st post is index click on topic to see it. 5th is a good place to start as it explains case airflow and how to optimize it by monitoring case airflow temp and adjusting fan speed curves.
