When we first reported on Noctua's integration of RotoSub noise cancelling technology in the run-up to Computex, many of our readers voiced their wishes to see real-world results. Most unfortunately, we were unable to provide any first-party coverage of this interesting step forward in cooling technology during the event, however Noctua did take the time to perform a quick and simple test, which it uploaded to YouTube.

The early prototype, a retrofitted NF-F12 120mm fan, is running at 2,500rpm in the video, up from the standard 1,500rpm of the current retail model. Whilst Noctua doesn't go into full detail of the results in its quick test, it states that its development goal is to achieve 80 per cent greater airflow and 120 per cent higher static pressure, whilst remaining at the same noise level and with the removal of unpleasant, high-frequency noise.

The firm hopes to have this technology in stores in either the third or fourth quarter of next year.

“Noice cancellation”? Surely you mean “nose cancellation”. :)

Sounds impressive. Looks like they're only removing a couple of wavelengths which are causing the most noise, but that's certainly a difference. I wonder how well it works when the base noise level isn't that high.

“nose” - Was that intentional? :p

Pointless, just another gimmick to waste more energy. A well designed vented case with a bit of soundproofing does the trick for me!

If not, Muphry's strikes again! If so… erm… OK then … <backs away slowly> … ;)

Massively improved airflow and static pressure would be great for water-cooling though - could really improve the cooling performance of all-in-one units with a single 120mm fan, whilst maintain the same noise level. Or presumably you could run the fan slower and it would be even quieter…?

cant see it as pointless, thats a massive difference and it seems that it will be a great contender for the gentle typhoons, may have to get some of these to test out compared to my noctua and GTs. I find the worst type of noise is the high pitch stuff, if its a low constant monotone its fine for me but when im hearing spikes or other just more higher/noticeable its god damn annoying.

How much energy does this noise cancellation tech require?. I think noise is more of a problem for me due to my case, all aluminium is great for weight but terrible for vibrations so i struggle to keep my system quiet as i would like it, if i could eliminate my pump vibrations id be laughing i think, then its just my psu fan which ive noticed more recently… ive tried putting sound proofing foam everywhere but it hasnt helped unfortunately. Time for a new case me thinks!.
