I don't like the MP I have either, even just the rear honey comb over the back exhaust caused them to howl but the XP are fine. Ending up buying 4 of them

I literally wince every time I read "static pressure fan" or "airflow fan" in a post.

Yeah....the little girl hentai avatar is really creeping me out....

Your thoughts about these fans is not what 99.999% of users, testers and reviewers say. I have to wonder if something else in your system is causing the noise to occur.

I have to necessarily buy new ones as i throw the older ones away... I could just use industrial ppc as intakes on top (yes i know it's not recommendable but better than nothing).
At 1200 RPM what bothers me most is not the fan blade itself but the HUM HUM HUM HUM of the motor. I could easily run these at 1400 under gaming conditions as gaming audio (speakers) would cover the sound even at nigh, but the HUM HUM is just unbearable.

I can understand this. I used the iPPC fans for a bit and found the motor noise unbearable. I'm not sure why you feel that moving them to the top as intakes would make this better?

And speaking of top intakes....they likely will do little or nothing to help. If you head over to the Phanteks case club thread, you will find a bevy of people who have tried every configuration imaginable with this chassis, and top intake never worked out well in air cooled systems - https://www.overclock.net/forum/159-...rs-owners.html

What i actually meant is that as i dont have older fans and dont want to just throw these in the bin (as they are pretty expensive) i thought about just moving them somewhere else...

Also thought of doing some case modding... removing the big grill circled in red, then drill the bottom for a intake fan that might help gpu maybe?
Also thought of this which is a simpler option (but idk if is going to interfere with bottom intake solution) and maybe move old IPPC fans on the TOP as exhaust to help CPU dissipating.
I also thought that i could use a x3 120mm fan setup instead of x2 140 by modding the front but i don't have such expertise... maybe someone made a custom phantek enthoo pro m panel without the CD cage? (blue part removed, only mesh)
Tell me what you think

Tell me what you think
I would either remove PSU shroud completely or maybe just cut out the grill area and cut a vent in bottom just enough in front of PSU so airflow will clear PSU cables. PSU cable would be as close to PSU as possible gpomg behind motherboard panel. Silverstone makes magnetic mounting filters that work well in places like bottom of case. I would also raise case so there is at least 40mm between case bottom and what it sets on. I use 30mm casters on 10x 30mm frame the size of case bottom (looks like a long picture frame). Remove all PCIe back slot covers, this give about 150% more airflow than the venting in slot covers give. You could also cut out all rear venting .. I've done this on some cases and it does help. Can also cut out mesh on PSU intake vent in bottom of case. 2x front and 1x bottom good 140mm intake fans will supply as much air to GPU and CPU as you should ever need. I wouldn't change front at all.

How big is the upgrade from the -SP to the -MP?

Anyone know how to use PWM to raise my noctua a12x25 fans to the 2000 RPM rated cycles. Theres something called Low-Noise Adaptor preventing them from going to 2000 and it stays at 1700. I dont know how to disable to go around so I can raise the fan speeds thanks!

Without knowing what motherboard you have and what control software you are using no, we don't know how to get 2000rpm.

If the 'Low-Noise Adaptor' you are referring to is Noctua one, it plugs into fan header and fan plugs into it .. just take it out and plug fan directly to fan header.
