New set of Case/CPU fans

**TechZ** · January 1st, 2005, 05:58 AM

OK, so the noise is driving me nuts, but I want to OC my 2.4 to a minimum of 2.8 and my Ti4600 too. Both of them have easy to use Windows apps that came with the h/w to OC.

Now I need a good recommendation on a CPU HSF Combo.

Nexus P4 Quiet CPU Fan <19 dB - PHT-3600
http://www.endpcnoise.com/cgi-bin//s...ml?id=kDcpGCvq

Seems reasonable, but its Al, no Cu, I want to get the maximum for spending all this money, cause I got to get it shipped to Bahrain too. $$$
Im looking for a good HS, better if its Copper, and a good fan to go with. Im not sure if I should invest in Artic Silver Paste or not, its not cheap, maybe I'll go with their (Artic Silver ) basic stuff.
As far as the fan is concerned, a 92mm would keep things quieter, and do a decent job at low revs.

As far as case fans go, I have 2 Rear, 1 Front, gonna swap them for quieter ones:
80 mm Nexus Quiet Case Fan (x3)
http://www.endpcnoise.com/cgi-bin/e/...se%20Fans.html

Its definately better than the stock fans that came with the case, and they would be quieter, I could go with normal case fans, better at what they do, but the noise is too much, and I keep the tower on the table, yes, on the table.

Your recommendations will be most appreciated.

and a good OC guide would really help, as Im trying to understand the relation between OC and memory(RAM) effects

I use the whisper quiet and it seems good
as to OC,ing

Seems after some good info, I'll be getting some more RAM, more precisely, 2x512 PC3200, though my board only does PC2100, it seems it will give it "headroom" to OC.

More $$$....

I don't have a specific recommendation but I once read a fairly detailed article (sorry, no link) that indicated the aluminum heatsinks with copper cores are the way to go. It said that the copper is more efficient at conducting heat on contact and the aluminum is more efficient at dissipating heat via radiation.

Dual-metals don't work out too well in practice. You end up with a copper disc that gets hot and an efficiency dropoff between the aluminum and copper. Thermalright (not Thermaltake) makes some great all-copper heatsinks that won't break the bank.

Example

You can slap a low rpm 92mm fan on that and get a decent amount of airflow for little noise.

thanks.

Im thinking of also investing in some Artic Silver Thermal Compound.

Also checked the SLK-948U and SP-94 out, nice, latter requires removal of MB, I want to keep it simple, and trouble free.

My dream machine is this Arcrylic Clear case with round LED cables. The case I'm looking at has five luminous and LED fans.
It will be cool and also a very cool nighlight. I'll be able to look inside and see what's up!
Of course, this means that I'll have to take my system apart and put it back together again to save on the cost, not exactly what I want to do anytime soon. I mean it is one thing to add a hard drive or an IDE card or a tape drive but to rip out the mother board?!
On second thoutht after looking inside, these new boards are not so difficult. Everything is movable. So I've got my eye on an Arcylic Case for $76.00. The cables and the fans will cost more than the box.

OK. Thats nice, nothing to do with my situation, but nice anyway

Get the Arctic silver don’t use the white thermal grease that ships with most heat sinks.

For OC try www.xtremesystems.org

**RejectionMan** · January 5th, 2005, 10:56 AM

for fans i use low RPM panaflow's

they run at 30 dB at max RPM (1700) and produce almost 70 CFM (120 mm) the 80mm are even quieter but you take a big hit in airflow, the medium speed 80mm are offer the best ballance between speed and airflow if a 120mm just wont fit.

Panaflo

Top it off with a fan controller and drive these bad boys down to 7 volts (low as they go) and you wont know they are there. The sound of a person breating is gerneraly considered 20 dB, your drives will make more noise than the fans running at full speed (at least my system does)

**TechZ** · January 5th, 2005, 02:02 PM

I want a 120mm fan(theyre low rpm's and QUIET), but I dont think theres that kinda place near the cpu, I'll check tomorrow as I have to put in a new DVD-Rom Drive.

Wow those Panaflows are great! The 90mm 430mA(yeah, quite high) model blows as much air as some of those 120mm fans (69CFM's)!

Those Panaflows are awesome! I just have to figure out now, which one in the 90mm range to get! The higher end ones take alot of juice, and they recommend not to use the 3 pin Fan Headers on the MB.

So whats a good/recommended CFM, considering its not gonna be running @ max all the time. And whats Intel's recommended Input Voltage (V), cause there are two versions in each size range.

Good stuff. Thanks Rejection Man!

**RejectionMan** · January 5th, 2005, 03:19 PM

Im using the low/Medium RPM, low voltage stuff (lower power so it works on fan headers)

by using every single fan hole on my tower i get the same CFM as lower number of high RPM modles, the benifit is they are all below 30 dB with out intriducing a Fan controller.

the 2 versions are 12 volt and 24 volt. their is no 24 volt supplie in a computer so you have to use the 12 volt units (also 12 V is blow the bottom threshold for the 24 V unist and will like not turn or will draw so much power as to break something)

as to mothe board headers the yshould beable to handle up to 3 watts

panaflow 120mm are avalible from www.vibecomputers.com seeing as how your quotine a CND cmpanay already.

**TechZ** · January 5th, 2005, 03:31 PM

Seeing as u know plenty on this stuff, mind recommending a good 120mm and 90mm Panaflow?

keeping in mind HS is good, and prolly gonna use Artic Silver, OC 2.4-->2.8. Details on MB, check Sig.

Objectives:

Make it quiet
OC ready

Requirements: 120 mm or 90mm Fans

Willing to: replace CPU HS and all exisitng Case fans

The facts:

-the H600 case has 5 spots for 80mm fans (2x rear, 1x front, 1x over CPU, and 1x side near HDD)
- the 400 W power supplie has 1x 80mm and 1x 92mm fan)
- 20 dB is considerded the volume of someone breathing
- 40 dB is considered the volume of someone wispering
therefore ~30 is white noise and should be our goal
FYI drive noise wil be around 30-50 dB and will be what you hear when its done.

The brutal truth:

its too long! What tools do you have and what are you willing to do to your case (modify the inlets/outlets)?

required tools:

hole saw or dremel
screwdriver (philips)
soldering iron
