If SFF like my ITX case with 5800x3D yes every bit counts. Airflow quite poor so how much u need to undervolt is less if your fans betterIs T30 for case fans a big difference?
In terms of noise, its noisier than my P12, to the point where its quite audible. Or it could just be my sensitive hearing.Is T30 for case fans a big difference?
I agree. It is very quiet. I won't say there is no noise, but it is soft.Arctic P Series Full 100% no noise at all
No. Once beaten twice shy. In fact, I got Corsair ML fans twice, and both times I had to admit they were mistakes. There are better fans out there. Don't take it from me, but if you look at reviews for best PC cooling fans, you generally see familiar names like Phantek T30, Noctua, Arctic P12, Gentle Typhoon, etc, but not Corsair.Have u tried the new corsair ml elite compare to the new t30?
The airflow will be stronger, but I don't think it is a must have as a case fan. You may realize some slight drop in temps overall as a result, but I feel it may not be worth paying 3x the price of a P12/14.Is T30 for case fans a big difference?
P12 only goes up to 1800rpm. T30 goes up to 3000 rpm tho default max is 2000 rpm. But if you restrict T30 to 1800 rpm it is also whisper quiet yet still better airflow because of 30mm thickness.In terms of noise, its noisier than my P12, to the point where its quite audible. Or it could just be my sensitive hearing.
But the airflow is worth it, i was seriously impressed by the air it was pushing through.
Sorry if i cant tell u in terms of temps comparison.
The max i'm willing to go is 1700 and i already think its quite audible as compared to the P12.P12 only goes up to 1800rpm. T30 goes up to 3000 rpm tho default max is 2000 rpm. But if you restrict T30 to 1800 rpm it is also whisper quiet yet still better airflow because of 30mm thickness.
No question that it is better but is it $35 better? Not even close imo u pay a premium even as u get diminishing returns
I don’t know if it’s the difference in design of the fan blades, but I feel the P12 are by far one of the quietest 120mm fans. In one of my previous rig, I’ve set all the 4 or 5 P12s running at full speed as case fans. The T30 is certainly not able to match the P12 in terms of noise even if I force it to run at 80% with a fan controller, and that’s in Hybrid mode where the RPM is capped at 2K. But it’s strength is not being very silent, but being able to balance both noise and airflow/ static pressure. At any given RPM, the T30 should always push more air, which means if you let it fluctuate it’s RPM based on temp, the T30 should generally run at lower RPM. But if your cooler is not capable of handling the heat and thus, forcing the fans to run at very high RPM, then it should become audible.P12 only goes up to 1800rpm.

Case fan noise is highly dependent on the intake grille pattern of the case coupled with the fan blade design. Even the most expensive Noctua's can cause a hum or resonance with certain patterns.I don’t know if it’s the difference in design of the fan blades, but I feel the P12 are by far one of the quietest 120mm fans.

Yes I am sure they are very good. But the T30s if u normalize for airflow level beats all of them. Normalize for decibel level or RPM, it will have more airflow:I don’t know if it’s the difference in design of the fan blades, but I feel the P12 are by far one of the quietest 120mm fans.

This is true. In my testing, I've tested the fans at 100% with no obstruction vs in a same case, i.e. the NR200. So I think based on both the tested scenarios, the result is fairly consistent. Having said that, the T30's fan noise is more of a very low pitch hum, and at least to me, it is not annoying. The downside of the P12 is that they lack rubber dampener and as case fan, I've experienced vibration and quite a bit at the top of the NR200. After swapping to the P12 BioNix, that problem went away, likewise, if I put a dampener on the generic P12, that problem went away as well.Case fan noise is highly dependent on the intake grille pattern of the case coupled with the fan blade design. Even the most expensive Noctua's can cause a hum or resonance with certain patterns.
This is correct. In fact the 3x T30s that I mounted in the front of the case to push air through the 360mm rad is very silent even under load. I've left the fan curve at stock, base on the BIOS settings, so I think the result is very good. But it can be audible if you are mounting it on say an air cooler because the temps are higher and requires the fan to spin up more often.Yes I am sure they are very good.

Use with my 240 AIO (generic Asetek) it is very quiet up to 1600-1700 rpm, very similar to what that test shows.
The real question is if its worth the money. In my opinion the answer is no outside of specific use case: small radiator, SFF, maximum overclocking. Ordinary case fan no point.

It suits radiator mostly because Phanteks also included screws that are longer. For air cooler, it is quite tough because they usually come with those thin metal clips that is meant for 25mm thick fans to begin with. If you have the old Hyper 212 plastic mount where you screw the fans on, then that might fit the thicker fan. Having said that, I feel the Fuma 2 is as optimized as it can be with the 2 fans that run counter directions. Adding a third fan may see a small drop in temp, but may also increase noise.Not many HS can accept T30 anyway. I got idea of mounting a T30 in front of my Fuma2 and a GT in the middle. But i will need lot of time to fine tune the speed so i give up.![]()
