Cooler master C700p front fans and replacements

apostolis_kt · 30 Mar 2020 at 10:17

Hello,

Could someone point me in the right direction.
Currently the case has 2 front 140mm fans and one rear.

I would like to add another one but possibly also change the 2 stock ones as they are loud on low and high settings.

Any recommendations for other brands?

I've been in the same boat for a while now. keep considering changing the front 3 ( i added another when i first built the pc exactly the same as the other two).
Ive decided to either go for a noctua 140mm but maybe wait till there next version of the 140mm.
Or go with a Arctic Bionix p140's. Ive just added the Bionix p120 to my gpu radiator and im impressed with it and not sure the extra price for a noctua is worth it. The p140 isnt that cheap but my impression of their fans is pretty high having used the p120.
Neither of these things is happening at the moment im just kind of planning a head for when i feel like doing it.

Arctic P14 PWM.
Bionix is just fancier looking more expensive version.

I guess thats right, only had experience with the Bionix version and the few extra features really work with a radiator but maybe not so much on the case.

I have here both P12 PWM and Bionix P120 and there's nothing in design why anyone looking into cost efficiency should pay for Bionix.
Blade geometry is identical, motors are same and with very smooth rotation there's no need for that rubber mounting.
And if needing that built in splitter in cable there's PWM PST version.

What are the specs of 3x stock 140mm case fans? I can't even find where it says what model fan they are.

3x 140mm good intakes are likely all the case fans you will need. Link below is to basic guide about how airflow works and how to optimize case airflow.

C700P supports traditional, chimney and inverted motherboard layouts. Which are you planning to use?

What CPU cooler and GPU do you plan to use? We need to know to be sure case flows the air they need.

Once we know these things we can give appropriate suggestions

Good point, I have already set it the traditional way so two fans fron the front bring air in, 2 at the top blow are through the AIO and out of the case and 1 at the back blows air out. I take it i need one extra fan to bring air in as atm more fans are blowing air out that air coming in?

I have an arctic freezer II 280mm, comes with 2 fans (and a tiny one for the vrm lol) that push air out the top of the case.

Got 1 Saphire Vega 56 Nitro LM plugged in atm but have a second one non lm version sitting so was planning to crossfire them - even though not sure as a few games i tested didn't do the job right.

Also a 3950x and 32gb 2 sticks of ram, currently on a enermax 625pro but just got in the mail a corsair HX1000 which came back from RMA as the previous one had horrible coil whine.

No idea what spec are the front 2 case fans i scoured quite a few sites and only thing i went by was the Guru3d review which does confirm what i found out that the case fans are loud and could do with being replaced.

First thing I see is too many exhaust fans. We intake fans to have a little more airflow than exhaust. If we don't the extra air exhaust fans are pushing out of case means dust will be leaking in vents/holes. I don't even use exhaust fans 99.999% of the time. Last time I used one was on a very small HTPC with exhaust being the only way to even have case airflow. The guide I linked in previous post should help you understand case airflow.

Top exhaust with CLC is fine. I would unplug rear exhaust and probably move it to front or bottom as filtered intake CPU is on CLC and GPUs will be air cooled?

So 2x 140mm intakes are needed to supply air 280mm rad is moving out, and 3 or 4 more 140mm intakes to supply the airflow 2x GPUs with 2x or 3x 80/90mm fans on each use.

Best fans are be quiet! Silent Wings 3 PWM 140mm high speed, but they cost £20.99 each. I like Phantkes PH-F140MP. They sell for £12.99-13.99 but will not be in stock until about 22.04.2020. I was using PH-F140MP 2-packs for £16.26 (£13.16 each) but the are also out of stock. Some people like Arctic P series fans. They only cost £5.99-6.99 and while not as nice as much higher priced fans do work quite wel .. again, out of stock on OcUK. If you shop around you can find 6-pack for twenty four to thirty quid.

I was looking into the Silent Wings 3 and a Noctua one.

The confusing bit is that the fan controller of the case accepts 3 pin fans i think. The case has a button to set on high and low. If i plug a 4pin pwm fan on one of the case fan controller what will happen? Will it work in low and high settings or will it go full speed regardless?

I much prefer using motherboard fan headers and set fan curves to vary depending on temp of CPU and GPU. That way they run slow and quiet except when system is working hard and need more airflow to keep things cool.

If you use 4-pin fan headers set to PWM (many 4-pin headers are not PWM and many others can be set in bios to function as 3-pin variable voltage (DC) or PWM. PWM generally give better speed control.

Apologies to wake up an old thread.

Would you happen to remember the spec or the model name of the identical c700p fan. I am trying to find what it is so i can compare specs with other fans. I am starting to look into Silentwings 3 PWM, Noctua Redux, and p14 PWM pst's atm. I read a lot of good stuff for all these and a bit hesitant as worried that Silentwings might not push much air in.

Not that i have issues with heat even with the current setup but if i can save off some degrees and be less noisy why not. The CPU will run 74ish on CB20 stock setup, and to be honest low or high on the case fans i dont notice any difference in temps.

I am also scrapping the crossfire idea, tried it and its a major hassle so will sell the second Vega. which means i dont need as much air flow as originally thought.

Right took a pic off of the front ones - the product no is A14025-12CB-3BN-F1. Cannot find anything in CM's pages of course i can find only on the auction site saying they are 1200RPM and 19db. If its just 19db then oh boy i am peculiar with sound because to me those fans sounds loud even on the slow option the c700p has.

OcUK has Phanteks PH-F140MP 2-packs in stock for £16.26 making them £8.13 a fan. PH-F140MP is PWM 1600rpm with 1.62mm H2O rating, but what makes them really good is in from 500rpm on up PH-F140MP has higher pressure ratings than all but a very few, even better than NF-A14. Higher the pressure rating means more airflow though grill, filter, cooler, radiator, etc, and 500-1100rpm is the range most of us use our fans.

https://www.overclockers.co.uk/two-...140mm-fan-radiator-performance-bu-003-pt.html

Here's chart of NF-A14 and PH-F140MP with similar rpm matched to make it easier to compare static pressure at similar rpm. All NF-A14 perform same at same speed, so ignore all data at speed above 1400rpm.

Sorry only just seen this, I dont know the specs of the fans but I reckon any decent newish fan will be better then them. The arctic p120 i have in the back of the case seems a lot better in quality and noise, and i reckon pushes more air then these 120s. I still haven't replaced mine yet but i will.

doyll · 7 Jun 2020 at 13:37

Not sure where above quote came from, but if your case is C700P, I think stock case fans have same impeller model# R4-S4S-10AK-GP fan Coolermaster recommends for this case.. with a pressure rating of only 0.82mm H2O @ 1000rpm, barely enough to flow just a little air through restriction of grills and even less with addition of filter. Good case fans like PH-F140MP are more like 1.0-1.3mm H2O @ 1000-1100rpm. Key to good airflow through grills and filters (like in our cases) is all aobut fans' static pressure rating, not it's unrestricted airflow rating. The higher a fan's static pressure rating (at normal use speeds) the more air it will flow through grill and filter resistance.

Most who have tried Arctic P series fans are happy with them. While not a great fan they are a decent fan. Many owners who have purchased several fans have commented about all not running same speed on same PWM signal or voltage, some have gotten defective fan too, so quality control is not the best. But they can be found at quite low prices if you shop around, often even lower in 5-packs.

Just put an extra fan i got from MM a silentwings 3 1000rpm at the front. So at the moment i kept the 2 fronts that came with the c700p, it sais on them 1200rpm was just wondering. The bequiet is quite less noisy compared to the others, not sure how it goes with air flow although cpu now is a bit cooler when gaming because possibly an extra fan on the front top is blowing air close to the cpu AIO.

Yeah i will look into replacing the CM ones at some point, not sure if i will get more silentwings though or the PH-F140MP i missed on the offer although not sure i like them in white. If i keep silentwings 3 would it be better to get the high speed ones?

doyll · 7 Jun 2020 at 20:53

Yes, while most of the time 1200rpm is a little faster than we may sometimes need. The higher speed model can come in handy in those rare super hot summer weather days when filters are dirty when running a real heavy load and we need 1300rpm maybe even a little more to keep things cool.
