Quiet fan for a tbred 1700.

[BG4533]

I am doing some case upgrades and I am trying to create a very quiet system. I am purchasing an Antec Performance Plus 1000, ANtec Treuepower 430, 5 NMB 80mm case fans from SVC, and a 80mm CPU fan to go on a volcano 7 (the current fan is a no name generic one). My current cpu temp is about 42 degrees, but I would like a quieter fan that could keep it as roughly the same temp, if not cooler. The fan is preferably from SVC since I am already planning on ordering from then. Would I be better off using 2 more powerful slightly louder fans or the 5 NMBs in terms of both noise and airflow? If anyone has any suggestions about the HS fan or even the case fans it would be greatly appreciated.

Thanks, Brian

I don't think it is your fan. I just installed a t-bred 1700+ for my friend and we used SK7+ with a 2000RPM fan. The temp is mostly at high 30's and low 40's. Get a better HS like SK7 and you can use low RPM fans.

I agree, the best part about Thermaltake heatsinks is the fans (and the case fan 2 is the only one I bother with), so you may wish to consider getting a decent heatsink for a quiet fan. The SK-7 has been on sale at SVC for $20 for a couple of weeks now.
I'd be cautious about putting a 18cfm NMB on a heatsink, but I'd give it a shot as a trial anyway, especially considering the price tag on that particular fan
If not, go with the panaflo L1A on the heatsink.

Good results with SK-7 and NMB fan on stock (non-o/c 1700). On A7N-VM (?) it's low 40s with poor case ventilation (PS fan only).
I'd be really surprised that you'll need lots of case ventilation (one or two NMBs exhausts should be all that is required, if at all). I was really impressed with how cool the 1700 Tbred A runs compared with my 1600 palamino. A friend of mine got the AMD retail, and the stock cooler is something I wouldn't even use on a 1ghz Tbird. Another friend got an SK7, which I was very impressed with.
The NMBs are the quietest fans I've had (panaflo and stealth, no 20 dollar papst (sp?) for me), but they move less air. I would use more of the NMB fans than getting 2 louder and faster ones. HTH

Thanks for the info, keyeye.
Sounds good, except I always advocate a balance of case airflow (ie same amount of air going in as out), or more going in than out when a balance is not feasible. With the usage of fan filters on your intake(s), this will help reduce dust buildup inside the case.

I think I am going to hold off getting a Heatsink and fan until I get the rest of the system set up. I would like to do some "comparative studies" with all of these changes. Right now I have an Antec midtower case with no intake or exhaust fans. Once I get the new case set up, I presume I will see a little drop in case and CPU temp. I will probably end up buying either a SK7 or SK800 and putting a Panaflow L1A on it. I would like to have at least a little extra room to put a faster processor in.

Thanks for all the help,
Brian

godmare, avoiding dust buildup is a good reason to have positive pressure in the case. I just happen to like as few fans on as possible, and two exhaust fans are, I believe, more efficient than one intake and one exhaust. To each his own.

Hate to jump in here, but it sounds as if you guys are big fans of the SK-7, which I've read good reviews on. As for the fan to put on top of it, I read a review that implied that putting a standard 80 mm case fan on it was not a great idea. What would you guys recommend putting on the SK-7 for someone more interested in quiet operation than anything else? I also have a 1700 Tbred.

80mm not recommended? Can you point me to an article or post where that is said?

"S<FONT face=Arial>o the SK-7 is clearly up to Thermalright's high standards. It performs very, very well with medium power fans, and will utterly humiliate most of the competition if you give it a stupidly powerful fan instead. Heck, this thing'd cut it for overclocking even with a super-quiet low power 80mm case fan on it."</FONT>

Here's the link to the whole article: http://www.dansdata.com/coolercomp_p5.htm#slk800

I guess I didn't mean to imply that 80mm case fans weren't recommended, just that it seemed like he was suggesting they were underpowered for the task. I didn't know whether there was a difference between fans intended for case use and fans intended for CPU cooling.

That sounds like a plus to me for the SK7 and low powered fans. A lot of HS would cause the processor to burn up with a Panaflo or other weak fan.

There is no difference between case and HS fans. I dont think many people would use TMD fans for cases though.

Unless, that is, they are having a problem with insufficient noise.

How come I can't get any sponsors for my new websites, www.noisypc.com, or www.loud-as-hellpc.com ?
