Fan Headers?

cyberspyder · Post by **cyberspyder** » Thu Aug 17, 2006 2:52 pm

Hi, haven't posted in here since i got my new WC setup, but here's the problem. i'm building a quiet Core 2 Duo system for my aunt who has a budget of $2500. the specs are:

-Intel E6300 Core 2 Duo
-Intel P965 motherboard
-2x WD 250 GB SATAII hard drives
-OCZ DDR2-667 ram (2 GB)
-Antec SOLO
-Antec NeoHE 430W power supply
-2x NEC ND3550A DVD burners
-Scythe Ninja Plus
-XFX 7600 GS (passive model)
-Hauppauge TV tuner (PVR 150)
-2x Nexus 92mm fans (for the front intake)
-maybe a Nexus 120mm fan for the exhaust if the stock Tri-cool is too loud
-Acer 19" widescreen monitor (700:1, 5 ms)
-Logitech MX3000 Keyboard/Mouse combo
-Logitech Z5300e speakers
-Creative X-Fi Xtreme Music soundcard

here's the problem. since i have a total of 4 fans running at the same time, is it wise to plug them all into the motherboard (it says on intel's website that there are 4 fan headers)? some one mentioned 'burnt traces' but what is it? help plz (ordering this weekend). i'm also sure that this is the wrong forum to post this in but my problem is centered around the fans.

If the motherboard has 4 fanheaders it should take 4 fans without any problem. Otherwise it's broken in some way.

I can't recall anything about that problem but possibly it's when people connect to many fans to 1 head and the motherboard tryes to supply enought power to them all in lines that isn't done for it. Those copper traces are only thick enought for a sertain amount. Just a guess.

Why get that case? Wouldn't Antec P150 be a bether and cheaper choise?

Will he overclock anything? Otherwise Corsairs value RAM (or simular) will be cheaper and enought for most users.

Consider most people in this forum with Antec cases replaces their tri-cool fans with Nexus you probibly want to order those right away. A fancontroller might be a good idea as well

*she* doesn't like the white+silver combination. also, a fan conroller will mess up the 'understated' look of the SOLO where there's only the dual DVD burners visible. perhaps the Zalman fan mate might work. will it work if i daisy chain the two 92mm fans to it? BTW, i couldn't find any DDR2 667 value ram from Corsiar or OCZ so the OCZ Gold is my next choice, and for $188, a steal too. can i adjust the fans through Speedfan? or is there a PCI fan controller?

Oh, I forgot that SOLO is the black version of P150.
OCZ doesn't have any cheap memorys I think, overclocking is their trademark. Depending on where you are buying from they probibly have some cheaper ram. Just a tips to save some money

Speedfan can change the fanspeed IF the motherboard supports it. And they usualy doesn't on all fanheaders. And it isn't a very good solution to my experience.
Zalman Fanmate 2 can be hidden inside the case or on the backside of the case.

so does the Zalman Fanmate support multiple fans?

If you buy Y-cables then it support fans up to 1A. Most fans draws about 0.2-0.3A if I remember correct.

BTW I have 2 120mm Scythe fans connected to 1 fan-head on the motherboard throught a fanmate and a Y-cable. The only "problem" is that I can only monitor 1 of the fans but since they are about the same rpm (+-10%) it doesn't really mather

You probibly want 3 fanmates and 1 Y-cable. 1 fanmate to the cpu-fan, 1 to the 120mm fan and 1+Y-cable to the 92mm fans.
Intake fans isn't really usefull tho. Rarely provide much of effect. If they are to slow in compered with the exhaust fans they can acctually block the airflow a little.
They usualy lower the HDD temps with 1-3 degrees C only

No, one fan per fanmate unless you hotwire another fan into it.
But... they only cost a few bucks each, and are really small (probably small enough to fit behind the mobo tray, depending on the case).

the two nexus 92mm fans are rated for 27 cfm at 19 dba, which matches the 36.87 cfm produced by the nexus exhaust fan, so i shouldn't have a problem. however, i have another quetion. since we all know that the human ear can't hear below 20 dba, is it ok if i run the 2 nexus intakes at 12 V (regular speed)?

We do anything above 0dB. We probibly couldn't point out anything below 10dB and we doesn't hear any difference on between 2 sounds that's 1-3dB between, they would sound just a strong.
I guess your confusing it with sounds above 20.000Hz. That's a difference mather.

How much silence people want is subjective. People think my computer is not even heard while I think it's way to noisy. I doubt it ever hit's 25dB.
So the only correct answer is to try and see. Most people wouldn't hear them at 12V but some will. I doubt anyone hear the engine but rather the windrush is to be blamed.

Soundlevel is raised when installed in a case as well. 19dBA might be correct in free air but in a case it might be 25dBA

If this answer has any uncleared stuff it's becourse I just woke up

There is one bay-based fan controller that might possibly match the SOLO, the Thermaltake Hardcano 13. http://www.performance-pcs.com/catalog/ ... ts_id=2289

alright, thanks. however, i think i'll go with the Zalman Fanmates.

cyberspyder · Post by **cyberspyder** » Mon Aug 21, 2006 6:55 pm

also, regarding the 120mm and 92mm fans, should i go with the Scythe S-Flex series? they have higher CFM ratings at a lower noise level. also, should i scrap the ninja for this: Thermalright HR-01-775 LGA775 Fanless Heatsink Heatpipe Cooler? is its performance worth the $10 price premium?

Scythe fans are similar to Nexus, often cheaper, and if you're going to undervolt them anyway...

Re the HSF -- check our reviews. They have both been reviewed. Short answeer: Ninja is king, only Thermalright Ultra 120 edges it.

cyberspyder · Post by **cyberspyder** » Tue Aug 22, 2006 5:00 am

which one undervolts better and retains the most performance?

Wow, your aunt needs dual DVD burners? I wish I had an aunt like that.

Regarding fan control/noise, why not dynamically control the fan speed based on what the user is doing at the time.

how? besides, it's too hard.

Dynamic fan control is built into your motherboard choice via the Intel QST feature.
