I am going to buy new fans for my TRUE heatsink and I was wondering if these fans would be louder then an Xbox 360? And also would there be any conflict(s) if I buy a fan that blows out a lot more air than my rear exhaust can take out? Example: my rear exhaust takes out 49CFM at 1200RPM and the new fans on my TRUE would be at 114CFM 2705RPM. http://www.newegg.com/Product/Product.aspx?Item=N82E16835705004
Jet takeoff (200 feet) 120 dBA Construction Site 110 dBA Intolerable Shout (5 feet) 100 dBA Heavy truck (50 feet) 90 dBA Very noisy Urban street 80 dBA Automobile interior 70 dBA Noisy Normal conversation (3 feet) 60 dBA Office, classroom 50 dBA Moderate Living room 40 dBA Bedroom at night 30 dBA Quiet Broadcast studio 20 dBA Rustling leaves 10 dBA Barely audible
I'm sorry.. rustling leaves is quieter than a bedroom at night? If there was someon in my bedroom rustling leaves at 3am it would wake me up, not be hidden under the room's ambient noise... which according to this is 20dBA noisier. Load of crap Car interior also... this neglects to mention that car interior noise is usually measured under acceleration in 2nd gear.
^ Agreed. My room at night is ~14dB. Sorry I don't have that as dBA. I know this because I did quite extensive testing when designing and building my HTPC. Unfortunately it's 18dB but there's nothing much else I can do about that without spending a lot more money.
It just depends on what you're doing in your bedroom at night. But seriously though, I try to stay under 20db as much as possible, and avoid anything over 25db like the plague. Also, I'm not sure you even need anything pushing 114cfm through a TRUE. It was my understanding that with that much airflow, your processor will run out of headroom long (like really, really long) before you're temps reach a dangerous level. Personally, I would look for something along same lines as your exhaust fan, maybe a few more cfm. That Panaflow you're looking at is basically server-class, so it's made to work for a long time with high cooling potential, but your ears will most likely suffer.
They'll be fine so long as you run them on a fan controller and turn them right down for day to day, however they will be clearly audible when turned up, even when playing games with the sound on. Why go for something with so much cfm? Could you not make do with 60-70cfm and use a fan controller to take them down to near silent operation for day to day use?
Im really not to savvy with using 3rd party fan controls, that's why I usually go for something that already has a high RPM, CFM, and unfortunately dBA. Would I see any temperature decrease when I replace my current Push/Pull fans that run at 1200RPM, 49CFM with the 114CFM fans in push/pull also?
Sorry, double post. Did find a review by sno.lcn on the page you linked to that seems to verify my assumption:
To be honest I find my PC noisy and it has all Sharkoon 1000's at low fan speed... 45dB will be very loud (or at least for a PC) Remember a conversation noise isn't annoying, constant whining of fans is. Very I vote quieter fans myself
Intollerable my ass, anyone who has been at a Rock/Metal gig/festival knows that level of noise (depending on the venue speaker setup and band anyway)
100dB is "painful" to the ears according to the definition. Also, dB is a logarithmic scale, so it's hard to compare...
Forget it, that fan is LOUD. I just had (2) Kaze 38db 110+CFM fans on my TRUE. Took them off and went back to the stock Thermalright fan (28db, tr-fdb-12-1600). Huge difference in noise, HUGE. Difference in CPU temps? Zero. (I'm running an i7 920 @4ghz). The rest of the fans in the case are pretty quiet (Antec 1200), so now the loudest thing is the eVGA Geforce GTX 295 when it's fan(s) go into high mode. Trust me, skip the 45dB+ fan, I'm sending my Kaze's back tomorrow along with the extra TRUE fan bracket. =] Oh, what seemed to really help? A> CrazyPC lapped the TRUE for $20 more. B> Arctic Silver Ceramique thermal grease C> Arctic Silver Cleaning kit. Now my rig is nearly silent, unless the GTX 295 goes into high mode. You can hear the hard drives a bit now too when they're grinding hard. (RAID-0 Seagate Cheetah SAS 15.6k 15k RPM drives). 45dB+ = BAD 28dB = Good
Depends. fast, 70mm fans are a nightmare, but 120 fans are a deeper, whooshing wind type of noise rather than a whining noise that you get from small fans. Far less annoying.
