Replacement fans for Thermaltake Water 2.0 Extreme

post #1 of 5
Thread Starter 
I recently built a new machine (see signature for details) and decided to try out liquid cooling for a change. After installing "the mod" (using a Kuhler 620) on my GTX 480 (when it was still in my previous build), I opted for the Thermaltake Water 2.0 Extreme AIO as my CPU cooler for the new build, and am very pleased with it so far.

My only gripe with it is the noise level of the stock fans. There are four fans in my case:
2 stock fans on the Water 2.0 Extreme (using "silent" noise profile in the included fan control software, I can still hear significant "whoosh"ing)
1 stock fan on the Kuhler 620 (undervolted via mobo/bios settings and is almost silent)
1 stock/reference/blower-style fan on the GTX 480 (set to 30% in MSI Afterburner, also pretty much silent)

Using the "silent" noise profile in the included Thermaltake Fan Control software makes the Water 2.0 Extreme fans sound much better than using the "extreme" setting, although these fans are still quite a bit louder than either of the other fans in the case.

I've done a decent bit of research regarding the importance of static pressure for radiator fans, and clearly the stock fans are designed with static pressure in mind. However, with the temperatures I'm able to achieve just due to having such a large radiator, I'd be willing to sacrifice some performance in the interest of having an even quieter machine.

In particular, I'm interested in the Scythe Gentle Typhoon series of fans. It seems like the often recommended AP-15s (1850 RPM) would likely be louder than the stock fans at their lowest settings (~1200 RPM), so those are a no-go. Would a pair of 1150 RPM AP-13s be sufficient for cooling a high FPI radiator (~20 FPI) like the Water 2.0 Extreme? If not, would the 1450 RPM AP-14s be good enough while still hopefully remaining below the "silent" threshold? Would the acoustic improvement of the GTs over the stock fans be enough to justify their cost?

The results in Martinm210's thread at xtremesystems.org seems to say yes to these questions, but I'm not sure if his tests were done using a radiator with such a high FPI.

I also don't intend to use a fan controller as I don't have room in my case (Bitfenix Prodigy), so the fans would likely be running at their full 12V speeds.

Clearly, the topic of silence is extremely subjective, but subjective answers are better than no answers at all, so any responses would be greatly appreciated!

Thanks!

i had the same problem as you and i also have a bitfenix prodigy. i got corsair sp120s and im extremely happy with them. they move more air than the stock fans and are significantly quieter. i would highly recommend them even though they are a little more expensive

Sorry to revive this thread, but I'm having this issue as I type.

Basically, in an ill-fated dive into my system (I'll skip the juicy, action-packed details ha ha), I busted one of my fans and need a replacement. I can't find the originals; however, since this PC is in a music project studio, I wouldn't mind getting the noise level down...

thekid, what did you decide upon? did it work well?

DizZz, you said you had the same case... do you also have the Thermaltake Water Extreme 2.0?
Also, can you provide a link to the proper fan for purchase? The one I found searching for that name seems to have a higher noise rating than the original Thermaltake ones....

Yes I did have the Water 2.0 Extreme as well and it was a great combo. I had the sp120s for a little while but they were a little loud for me so I changed them out to noctua nf-f12s which were the perfect balance of airflow, static pressure, and noise for me. They are really expensive but well worth it if noise is a problem for you. I would also look at Scythe AP14s if you want a little cheaper fan with an excellent noise/airflow ratio.

I actually followed DizZz's advice and went with the Corsair SP120 Quiet Edition, which have treated me well so far. I'm not sure if DizZz went with the Performance or Quiet edition, but the Quiets have certainly seem to have lived up to their name from my experience.

The fans operate at 12V by default, which ended up being a bit loud for me (though still a bit quieter than the stock fans, if I recall correctly... this was 6 months ago, so the test results aren't exactly fresh in my memory...). Notably, also included with the fans are 12V to 7V 3-pin adapters, which help decrease the fan noise quite a bit, but at the expense of cooling performance; however, given the already outstanding performance of the TT Water 2.0 Extreme, I was willing to sacrifice a few degrees in order to have a quieter machine.

Also, I should mention that the SP120s have 3-pin connectors, while the TTW2.0E has 4-pin PWM fan headers. From what I can remember, I don't believe the TTW2.0E's headers are capable of adjusting fan speed using variable voltage, so I connected the fans directly to my PSU using a molex to 3-pin adapter (with the 12->7 V adapter attached between the molex to 3-pin and the fans themselves, as well). This means the fans on my TTW2.0E are always on and run at a fixed speed, regardless of CPU load/temperature.

All-in-all, I'm still not sure what (if any) significant advantages these "high static pressure" models from Corsair really have over the cheaper Scythe fans, although for what it's worth I've had the SP120s for about six months and hadn't even thought about them between the initial setup and reading your message today, so that would seem to indicate that they're doing their job well.
