T.R.U.E 120 .... any users running 2 x 120mm as "Push & Pull" Fans ... ?

Ben Ifin · 31st January 2009, 12:28 AM

Hi

I currently run a TRUE 120 with 1 x 120mm Noctua NFP12 fan - it is quite literally silent - my HX 620 P/Supply is louder.

I am looking to set up a O/C i7 920 in a closed well ventilated case and am hoping to get to 3.8 <-> 4.0gig and my plan is to use my TRUE 120 with 2 x 120mm Noctua NFP12 fans ....so .......

Questions

=> if I run a 2nd Noctua NFP12 on my TRUE 120 - so there will be 2 running in a Push / Pull setup - will this increase noise levels by much if at all ?

=> is there anything to watch out for when running 2 x 120mm fans on a TRUE 120 in a Push /Pull configuraton ?

=> lastly, as a general rule, by how much is CPU temp reduced if a 2nd 120mm fan is added to a TRUE 120 in a Push /Pull configuraton ?

Many thanks,
Ben

To get a more accurate response you should include the CFM ratings of each fan

Cheers

Using such config myself http://i4memory.com/showthread.php?t=12855

Thermalright Ultra 120 Extreme + LGA1366 Bolt Thru kit + 2x 120x38mm Scythe UltraKaze 2000rpm 87cfm fans in push/pull

mismatched fun http://i4memory.com/f83/6x1gb-corsai...rclocks-14112/

Max 3d benchable @4473Mhz HT enabled and bench Super Pi 32M @4652Mhz. Max CPU Validation on air @4769Mhz http://i4memory.com/showthread.php?t=13746

1. not much diff
2. watch module hs height and orientation of heatsink
3. depend on static air pressure of fans anywhere between 1-8C gain. Noctua NFP12 looks too weak to do much even with 2 fans for i7 cpus.. You'd want at least 75+ cfm per fan

-Opteron 170 @ 2.9g, 1.4v (>110W)
-Nexus Real Silent 120mm

Adding a second fan gave a ~2c drop - not worth it imo.

edit: also from a noise perspective, i wouldn't recommend using two of the same fan because they will resonate due to making the same frequency vibrations.

I've got 2 of those ultra kaze's on my rad, and they make way too much noise at full tilt. I spose you were overclocking pretty heavily

Ben Ifin · 31st January 2009, 12:44 PM

Hi eva

Given those load-temps - I presume they are under %100 cpu load- I gather you run your rig on an open bench and not in a closed case ?

Otherwise, those are amazing temps for a 4.0gig o/c 920 at full %100 load ?

Thanks,
Ben

guess comes down to what each person can handle in terms of noise..

yeah 100% linx load but in open bench.. haven't used cases in 5+ yrs heh i get more manageable temps in mid 60s with 3815mhz at 1.232-1.264v

Linx will stress cpu more than Prime95 by as much as 5-8C depending on cooling and ~8-10% more power draw

Count me in, I am using some 2 half size 120mm fans.

Ben Ifin · 31st January 2009, 4:39 PM

Hi chainbolt

You wrote:- " ...... I am using some 2 half size 120mm fans ....... "

Not sure what you meant by this ? Which actual fans are you running ?

Laslty - I'm wondering it rather than going to 2 x 120mm x 25mm on my TRUE for the i7, if 1 x 120mm x 38mm might be better / overall quieter ?

BTW chainbolt - your "signature" suggests you are selling [ or going to sell ] a i7 920 maybe plus mb and maybe plus ram (?) - if so, please PM me the details.

Thanks,
Ben

Ballistics88 · 31st January 2009, 11:27 PM

Hi.
One this to watch is attaching the fans to the heatsink while the motherboard is still in the case. Now that was annoying.... my big hands and the the wire fans holders dont get me started....

Ravennoir · 31st January 2009, 11:32 PM

I just got two of the new fan clips for the TRUE120 (the plastic shrouds)

I havent noticed much change, although it has been really hot and my CPU hasnt really gone up much at all.

I also am currently only running the fans from the Thermaltake Armor

Im sure these are pretty crap, but im hoping to upgrade soon. any suggestions for fans to get (i would prefer LED ones)

This is what I'm running, whether it's better or not I can't say. It is very effective though.

You do realise Herr Chainbolt isn't in this country?

TaroT · 1st February 2009, 9:52 AM

i have a normal 2000 rpm fan pushing and tried a pull setip but it made no difference.
What did drag the heat through is the 120 mil DELTA THAT IS MOVING AROUND 220CFM AND IT REALLY HELPS ALOT...WHAT...SORRY...NO ABOUT 9 OCLOCK

needless to say it is a tad loud but then it is 40c in here

Hens · 1st February 2009, 11:04 AM

I am running a lapped true 120 on a lapped cpu in a push pull config. Due to my case and mobo I had to mount the true in a horizontal position which is far from ideal.

I am holding it all together using zip-ties.

e8400 @ 3.6 with stock volts (1.25 in bios 1.2 after vdrop)

I get around 58-60 linpack load and idle at around 45-47 with ambient temps of over 30.
