Airflow is simply displacement; for air to come into case, air must be leaving case ... Think of the air around us as water... No, this is wrong/bad. Air is a compressable gas, water is not. Airflow is something that nature creates sponatneous when there's a difference in air pressure between two p...

To hear a decent quality fan at 300rpm is not common .. and requires very sensitive ears being quite close to it.
Are you sure it's the fan making the noise or is it maybe the grill effecting airflow that is making the noise?

What is your system, including case, CPU cooler, etc?

What is your case airflow like? Ideally, what is the air temp going into cooler compared to room ambient? Many stock case fans / case fan setups cannot supply the cool air cooler need and they end up using heated exhaust air that is 5-10c even 20c warmer than room .. and every degree warmer the air ...

I agree, $50 is a good balance of performance and price. But getting a good air cooler is only half of the job, the other have being setting up case airflow to supply CPU cooler (& GPU cooler) with cool air at or near room ambient. The reason is that for every degree warmer the air is going into coo...

Nice build! The TY-147B slotted housing is supposed to change sound and airflow slightly, but I didn't notice any difference in any of the applications I tried them in. Here are specifications. TY-147 B has a different bearing, slotted housing and is 1dB quieter. TY-147B Dimensions 140 x 152 mm Inst...

Are you monitoring the air temp going into CPU & GPU coolers? I'm going to make a wild guess you have not done this yet, and that the air temp into cooler is higher than room .. especially the GPU. ;) I'm guessing your 2x AP181 fans are not able to flow /push enough air to keep cool airflow to fans ...

Hello, What CPU cooler (low noise / reasonable price) would you recommend for an i7-6700. My case (bought in 2011) is a fractal design define mini, micro atx The motherboard will certainly be Asus B150M-C Thank you Scythe Kotetsu is indeed a very good cooler. Where do you live and how much do you w...

I really wanted to buy this CPU cooler but can't; it's either sold out or Amazon doesn't ship it into my country. Is there a good alternative for Cryorig H7, so an excellent fan no higher than 145mm, with a big fan. P.S. Please don't say Macho 90 again, as it doesn't exist in my country. Well, with...

Kinda hi-jacking, but do you think the 680 is at a good used value point right now? Or is there something better in same price range? Here in UK asking price is £120 on 680. For comparison, a new MSI GTX 960 Gaming 2GB is £160. I'm seeing used ones on eBay for $160 in US. Depending on your monitor ...

I think it would be easier to use something like a Raijintek Morpheis, Alpenfohn Peter, or Prolimatech MK-25 with a PCIe extension. Make some sort of mount for the GPU to be aligned with motherboard and with fans drawing air from cooler and exhausting into a duct to vents in side of case. This would...

Yeah, nice idea to move air out from motherboard, but those 5x 40mm fans did a lousy job in the noise department. Would love to see 3x or 4x width coolers moving front to back or bottom to top, but the don't seem to exist.
Dreamed up this cooler design with 2x fans on end.

Thanks for that. I'm looking at a used 680 from myself and moving my 580 to wife's machine. My only complaint with it has been not being able to idle it down slower. It's not terrible, just seems a waste to have such a good cooling system and not be able to lower fan speed to take advantage of it wh...

Sorry for reviving the dead, but is it possible to do this on the older ENGTX580 DCII/2DIS/1536MD5?

Pretty amazing how loud HDDs become when fans are quiet. :D How tight are the HDD mounting screws through their rubber dampers? I've found the need to be almost loose. If they are even the least bit too snug the don't work as good as they can. This won't stop their clicking, but will usually quiet t...

Knowing a 2nd language is good, but it is better if you know English perfectly, like you Canadians do, regardless whether you know languages else. :wink: Beyond all, I always use the Google translator to write here. :oops: :) I'm aiming at that case because it has white LEDs (I do not know another ...

I recently bought a Scythe Fuma, which had two Slip Stream fans bundled. Their product code is almost that of the standalone: SY1225SL12M-CJP as opposed to SY1225SL12LM-P, and it has a grey colored fan. It also exhibited clicking, on DC and PWM as well. My older SY1225SL12LM-P fans I got for my Mug...

PWM clicking is often blamed on the fan because that is where the noise originates. But it can can be caused by PWM source (motherboard PWM design), PWM in fan, and even occasionally by power source (PSU). Some "PWM clicking" has even been tracked to fan blade design reacting with vent grill, cooler...

Imagine a Raven or Fortress rotated 90° to the left. It is the nearly same layout of a Corsair 400Q. Imagine a 400Q rotated... vice versa. I just used Corsair 400Q as example, and because I see it has closed holes in the front, floor and ceiling. That might be optimal to make the positive pressure ...

Think you asked this elsewhere, but answer is the same. Stay away from CLCs. Get a good air cooler and have no worries. At best, H110 might give you a couple degrees more cooling. Setting up your case airflow to supply component with air as close as possible to room ambient will generally give you 5...

I've found most of the time if good intake fans are uses no exhaust fans are needed .. and if needed it is more to change the case airflow patterns than to increase case airflow. By this I mean flowing a cool air supplying to component and flowing their heated exhaust out of case without it mixing ...

Yes, that comment was addressed to you. Just interested in knowing what speeds your intake fans are running at when the CPU and/or GPU is under load. The reason is I am just starting a Define R5 build and have not made any final decisions about fan choices or positioning yet. It varies depending on...

I'd be interested to know what CPU temps you get with this approach if you stress the CPU using Prime95 as SPCR did for the Quiet ATX Gamer, R5 Version and what fan speeds you are getting under this kind of load. Who are you talking to and what are you talking about. If it is me, please explain in ...

I ordered the Scythe Ninja 4 in the end with some Noctua NT-H1 thermal paste. I have to admit there was a moment where I was tempted to get a NZXT Kraken X61, but as this is a 24/7 long term system I just don't trust AIO water systems. I'm still concerned about the weight of the Ninja 4 and clearan...

so, just a bunch of links to another site?? :? Yes indeed. Done at the suggestion of CA_Steve The only reason I started this thread is because it was suggested I do so. The bold text at beginning of thread explains why. But if you think it should not be here, please feel free to complain to Steve a...

I thought this might be of interest to members. If you have questions, pleases post them here on spcr, not on OCN. If it was not such a time consuming job to move them I would post everything here instead of linking to each topic elsewhere. Maybe in time I will get it all moved, but for now at leas...

If it will be setting on the floor a open center castor base not only makes it much easier to move system to clean PSU filter, but greatly increases the airflow to bottom vents. Great idea. I plan to do this. R5 filter slides out the front anyway, but adding a bottom intake with the 2x front intake...

PH-F140HP should do a good job. I have used the PH-F140HP, but not the new PH-F140HP II. According to the specs they are about the same, but I would expect the F140HP II to be better. http://www.silentpcreview.com/forums/download/file.php?mode=view&id=1352&sid=6e0064f7c778d3df967d5e550ddb0429 Do kee...

What Steve said.

Define R5 is better than Define R4. To me the biggest improvement is bottom filter .. The whole bottom filter slides out the front !! No more need to pull case away from wall to remove filter out the back to clean it.

I would change the front intakes to better pressure fans to overcome the grill and filter resistance without needing too much rpm. 3x front and 1x bottom intake, all speed controlled based on airflow demands of CPU and GPU coolers. Raising the case so there is 40-50mm clearance not only increases ai...
