Silent fan advice

Yes, I am UK based. You are correct, we no longer have a Thermalright distributor. There is one internet source I know of.

I have HR-22 and new Le Grand Macho. I get slightly better temps with Le Grand Macho. Send me a trust message an maybe I can help

What a pity, the True Spirit 140 Power was my first choice of cooler (but didn't fit on my m/b). I can vouch for the fans though, very good products.
 
How do I know whether or not my Motherboard is PWM and my fans are PWM?

So from my limited understanding is that a PWM splitter will enable me to control fans so that when the temperature rises it will spin faster and if it lowers then the fans will also spin slower?

This is all automatic as well?
 
May I ask why the TRUE Spirit 140 Power did not fit?

It intefered with the top PCIe slot on my motherboard (micro-atx), I ended up having to choose a cooler with an offset design.

*Apologies OP, slightly off-topic.

Fans with 3-pin plugs are variable voltage, fans with 4-pin plugs are PWM. Most PWM fans function on variable voltage.

Motherboard is more complicated because while 3-pin headers are usually variable voltage (some are fixed voltage and some are pulsed 12v). Their 4-pin headers may or may not be PWM. It is not at all uncommon to have 4-pin headers that are fixed or variable voltage with no control in the 4th pin (PWM control is always in the 4th pin). To even further complicate it motherboard companies have repeadedly insinuated some of their 4-pin headers are PWM when in fact that not!

Add to this that most PWM headers can be set in bios to be PWM or variable voltage, and there is no standard among manufacturers as to what header is set at by default, and we have real mess to sort.

Tell us what motherboard you are thinking of getting and I'm sure we can tell you what the fan headers really are. There are many of us who have ran this gauntlet and figured out the answers. :D

Indeed, the TRUE Spirit 140 Power is very wide .. like 155mm (77.5m center CPU toward PCIe socket)if memory serves. Have you seen the TRUE Spirit 140 Rev.A? The finpack is offset so center CPU toward PCIe sockets is 69mm. It is also 6mm shorter (165mm instead of 171mm).

I have some fitted that are set with speedfan to come on in case of emergencies ( I was too paranoid to build it without) and they've been on about twice I think and that was when stressing my CPU under volt with an unrealistic load, even then they come on at 300RPM (Thermalright TY147a) to just move some air around. CPU idles at 25-30c depending on room temp, and during normal usage like gaming I couldn't get it to go over 55c with a room temp of 23c.

But yes, in answer to your question the only fans running in general use in my system are those on the Strix 980ti, and even they don't come on until 60c degrees, which is only reached when I game. PSU is the fanless Silent Flower 500W.

That's great news. The Nofan's one issue is its size.

What was really attractive about the Power was the cooling benefit in the 8mm heatpipe design, once that was no longer an option the field of possible coolers opened up a great deal. I did look at the Rev. A, ended up going with a NH-D15S.

A mate tested TRUE Spirit 140 Power against NH-D14 with TY-143 reference fans. The difference at full speed was only 3c cooler and at 1200rpm it was only 2c.

I do not have a D14 to run comparisons, but have ran TS140P to TS140rev.A comparisons and they are near identical. Only when pushing with extreme oveclock / heat does TS140P become better .. by maybe 2-3c. I really need to do some D15 to TS140P & TS140rev.A comparisons, but I don't have anything built right now that is pushing enough heat to really do maximum heat comparisons.

I have a Gigabyte Z77 UD5H I am just thinking of moving it into another case and perhaps then investing into some fans basically is what I was thinking.

I think CPU fan header can do both voltage and PWM control, (choose which one in bios). Sys fan header 1 is voltage control, and headers 2 & 3 are PWM control. Header 4 always runs at full speed. Assuming this is correct you could run a lot of PWM fans by using PWM splitter / hub with PSU power. These use the PWM signal from fan header and power from PSU so each header can control 7 or 8 fans.

What cases are you thinking about?

Phanteks Evolv or Fractal Design R5/S

Also is PWM the best way to control fans then I assume? what is the difference between voltage and PWM? I really am a newbie to this sort of stuff

I have older Define R2 and have built R3 and R4 cases. Define R5 has one really nice feature .. all bottom filters slide out the front!! No need to move case to clean PSU filter!!

I also have Evolv ATX and like it a lot, but PSU filter cleaning is a hassle.

I also have Enthoo Luxe and like it a lot too.

Enthoo Luxe and Enthoo Pro have two bottom filters so stock case has to be moved to clean PSU filter. BUT!! They can be taped together easily with acouple pieces of tape and Wallah! we have a one piece filter that slides out the front!

Is it obvious how much I hate having to move system to clean PSU filter? :p

Fan control by variable voltage versus PWM is arguable. PWM wastes less power because it is pulsing the 12v power to fan motor. Variable voltage uses resistors and transformers to lower the voltage, which wastes power and generates heat. A PWM powered motor will spin slower than a variable voltage motor, but the fan speed is also dependent on what the fan low speed limits and motherboard variable voltage and PWM limits are. I know people who use variable voltage only because their motherboards will allow fans to idle lower .. their PWM is limited to like 30% which tranlates to 700rpm while variable voltage will idle same fan down to 400rpm. These same fans on my aquaero 5 LT PWM will idle at 350rpm, but I can dial PWM down to 0% .. no bottom limit on Aquaero. ;)

Sorry to be so wordy with details, etc.

Out of all of those cases which one do you think is the best and why?

In terms of silence how quiet is the Evolv? is it noisy?

Can I assume you are talking air cooling, not water, and definintely not CLC?

Silence is relative. To me anything with a sound level below about 30dB is acceptable and all of them are about that level. The sound level is also dependent on components and load. The more powerful the CPU and/or GPU are the more heat they make, the bigger their coolers need to be, and more airflow to each is needed.

Obviously the case must flow at least a little more air than components use, but is isn't just how much airflow. Equally important is how the air flows in the case .. the paths cool air takes from intake vent to component and from component to exhaust vent. These paths need to flow the heated exhaust out of case without it contaminating the cool intake air.

Most all cases have front top and back venting, many also have bottom and side venting. For most air cooled builds front to back airflow is best (SilverStone bottom to top cases are the exception).

With this front to back the best is with a front intake directly inline with CPU cooler. Using top vents more often than not draws heated air up off of GPU into CPU airflow path.

Cases need lots of back venting, not just the traditional vent over motherboard I/O, but also around and over PCIe slot covers .. and PCIe slot covers too. This is so heated air coming off of GPU can move back and out of case rather than up around CPU cooler.

But I digress. All of the cases I mentioned are very good, but they are not the only ones. They are also not perfect out of the box. The Enthoo Luxe needs the front 200mm intake fan replaced with 2x intakes. Case comes with 2x PH-F140SP fans. I tried case by using them to replace the 200mm fan with good results. I ended up getting one more and experimented with 2x front intake and 1x back exhaust as well as 2x front intake and 1x bottom intake. The 2x front and 1x bottom with case's PSU cover removed worked best for me, but I also added a 30mm castor open center castor base (improves airflow to bottom intakes).

I love my Evolv ATX, but I did do some mods to improve airflow. I spaced the front out about 10mm to improve front vent area. This is easily done with some longer screws and spacers. If you go the Evolv route I an help you with this.

But I can think of half a dozen other cases just as good as these .. maybe a couple a little better depending on variables involved.

I had a very very noisy acrylic case before and when I first got my Carbide 500R in my eyes it was basically silent, I was so surprised by how quiet it was. I think my ears are more sensitive to it now though and I was wondering what it would like to be to have a case that is designed more for silence.

I have heard that it sometimes does not matter about the case that much as it depends on what components like the GPU and the fans and such.

Which is wondering if I could get away with using the Phanteks Evolv and having it still be quiet if the fans are quiet. I like the look and layout of the case inside the Evolv which is probably why I kind of want it to work but if there is a better option out there then please let me know so I can take a look at it.

I do not really plan to use a CLC because they are more noisy than traditional air coolers are they not? I do not really want to get into water cooling at the moment, since I am so new to this, maybe one day but I just want to replace my case at the moment.

Please do give me some suggestions of cases to look up that you think would be good.

Wow! A newer member with low post count who knows something! I'd love to discuss this over a pint or three. :D

Indeed, while a good case is important, the sound signature and level of components including fans makes the most difference. Grills are also a contributing factor.

I'm using an Evolv ATX and like it a lot. I am experimenting with spacing the front out 6-10mm to improve intake airflow area in hopes it will lower temps, and it does help, but not as much as I had hoped. Basically it shows the stock venting is not as bad as it looks. I am getting 3-6c better temps with the spacing.

Enthoo Pro & Enthoo Luxe cases are good. If silence is really important, the Define R5 is probably a little better, but it's fans would need to be changed.

I look at little things, like being able to clean filters without moving case from where it lives ( usually with it's back toward a wall .. and often under a desk). Bpth Enthoo Pro and Enthoo Luxe have 2x bottom filters, but taping them together with a few mm between them makes them into a single filter that slides out the front , same as Define R5. Evolv requires moving case out to pull filter out the back.

That is only a short list of cases I know are very good at reasonable prices. There are more I can suggest, like Define R4, Arc Midi, Enthoo Primo (much bigger), etc. ;)

Like you my experiences with CLCs have not been good. Between marginal quality, loud fans and not uncommon pump failures making it necessary to have a backup cooler handy I avoid them like the plague I believe they are.

Good air cooling systems for CPU are common, and there are some quiet GPUs too, just not as well designed. While tower CPU coolers draw cool air from front and expel heated air back toward rear vent, I know of no quiet GPU coolers using this simple concept of intake and exhaust separation. Instead they all dump their heated exhaust every direct into all areas of case. But we can overcome most of these problems with cases that have venting over their entire back area, like one listed.

I can't remember how many posts you need before you can setup your 'trust' (1st button, bottom right) and be able to send me private messages.
 
If your psu has a semi-passive fan mode the filter will only need cleaning very infrequently (my system is at stock with single gpu, 650w psu, and after six months it still doesn't need doing... I check when I'm feeling paranoid...).

How often filter needs cleaning is dependent not just the amount of air being drawn through it but probably more so by the amount of dirt in the air.

But no way will a filter stay clean for a year!

I have been running filtered systems for about 17 years now in all kinds of environments, desert, farm land under irrigation, humid city, dry city, rural humid, pets and kids, and single no pets or kids. Filters have always needed to be cleaned at least every month to 6 weeks. I suppose I could stretch that to every couple of months. But sometimes the got dirty and needed cleaning as often as every week.

But by all means, clean yours only a often as you want to ;)
