Fan selection?

[alkemyst]

I currently have:
Input:
3 x PC Power & Cooling Silencer 80MM #802312 (27 CFM / 20 dBA / 1700 rpm)
Exhaust:
1 x PC Power & Cooling Silencer 80MM #802312 (27 CFM / 20 dBA / 1700 rpm)
1 x 120MM fan inside my Corsair HX750 blowing out
CPU:
1 Panaflo 120mm FBA12G12L1A (68.9 cfm / 30.0 dB / 1700 rpm) on a TRUE

I am thinking of changing to

Input:
3 x Panaflo/ NMB 80x25mm high-speed fan Hydrobearing #FBA08A12H1BX 39.6 CFM / 32 dBA / 2950 RPM
Exhaust:
1 x Panaflo/ NMB 80x25mm high-speed fan Hydrobearing #FBA08A12H1BX 39.6 CFM / 32 dBA / 2950 RPM
1 x 120MM fan inside my Corsair HX750 blowing out
1 60mm Sunon PMD1206PMB1-A 52.5 cfm / 34.5 dBA / 8000 rpm
CPU:
2 x 120MM Scythe "ULTRA KAZE" DFS123812L-2000rpm 87.63CFM / 32.91dBA / 2000 rpm for my TRUE, push pull

It's inside an addtronics 7896A (similar to a SuperMicro SC750)...older server case.

Phenon X4 overclocked, 4890 overclocked, 1 HD, 2 Opticals, Wireless NIC.

I am hoping to get my temps more under control and not have a 'ton' of noise. My PC is dead silent now.

Your problem is the 80mm fans, and the 60mm should just be junked.

 

[alkemyst]

it's the case I am working with. Those are my options.

 

[MisterDonut]

You know what you need on your TRUE? Scythe GT. That is all. BTW, those Panaflos are going to have your ears raging.

 

[WoodButcher]

Got a dremel? at the very least cut out the fan grills but enlarge wherever you can, Move up to 92"s. I can vouch for the GT 92. If you have available 5.25 bays you could install a tripple HD unit with fan like one of these.

Buy a new case. Don't waste money on small fans. They make noise and don't push much air.

 

[Seferio]

You could also consider an 80mm Scythe SFlex fan such as http://www.performance-pcs.com/catal...ducts_id=25497.

Pushes lots of air, pretty loud but combine it with a decent fan control device to drop it to 50% or so and it's quiet.

 

[alkemyst]

I don't think going to 92's would be practical. My case has been dremelled and with the 4 ultra quiet 80mm I had, had decent airflow.

I will see how these fare.

Eventually I want to go to a new case, but I would be on the $300 side of things.

For not much more $$ than your talking about for fans...

Consider the CM HAF 932. Mondo amounts of room, nearly completely future proof, And TOPS when it comes to cooling. Comes with and abundance of fans already. Should be able to cool anything you throw at it short of 3 way SLI 470/480's without adding any fans whatsoever.

Prices have been around the $130 mark for week now, and can sometimes find for less.

JUST A PREDICTION-- July 4th sales coming up, more than likely will find someplace to grab this case for around $100 as seems like e-tailers are lowering inventory levels on this unit to make room for the now released HAF X(942). Would be worth checking the CM site for refurbished prices too. Recently was at $90-$100 there before the HAF X release. May see that again soon.

What are the temps now ? If they are in the normal operating range then don't worry about it. People tend to worry about high temps but that is because people relate to what we know. We are 98.6F so something 110F seems hot to us but to electronics its nothing.

 

[ehume]

Lordy! Expensive 80mm fans! Loud and push little air, y'know. Right now the Cooler Master store is selling a refurbished HAF 932 case for $99.

I have a bunch of 80mm fans I got in a variety of ways. They are simply not worth the money.

W/O windows means no hole for the window or the lexan is missing?

If I had known these cases cames with the fans already I'd have upgraded maybe. I'd have to deal with 2 beige SATA burners I just got...

The fans I selected are slightly louder than what I have and what I have I cannot hear from my listening position. My ceiling fan is louder.

W/O windows= solid side panel

2 beige SATA burners= paint.

Modelworks said it best, is your system failing? bluescreen? if not, leave it be. Why spend money to fix what ain't broke?

and believe meritline along with few other places sell just the replacement sata face plates, never mind untold thousands from fleabay. Sure if you check your local seller of the old crappy p2/win xp systems if they have a broken one or two, can you buy face plate for $1 before they throw out.

Testors model car paint, flat satin black or high gloss black, what a $1 at wally? and always handy to have for any chips or blemishes on cases.

 

[alkemyst]

sorry...other posts here about it.

I am looking to hit 4GHz or more...my system is hitting 69C+ on load with ambiant being around 78F.

If I can fix that with just fans it would be nice.

The added benefit of my current case is it cannot be removed easily from underside my built-in desk.

I live in a nice neighborhood. My home and my neighbors were targeted last year for a total clean out.

The components I could care less about, but the data loss we suffered really sucked.

We have gone to off-site storage now.

Ok, HAF X/HAF 932 are NOT small cases, but understand more of the predicament.
Haf 932-Dimension (W / H / D) (W)9.6" X (H)22.5" front half, 21.5" back half X (D)22.7"
Haf X-Dimension Main unit: 230 x 550 x 590 mm / 9.1 x 21.7 x 23.2 inch

Problem is, part of the great airflow includes the top exhaust fans.

Biggest thing in your situation is CFM=air movement.the higher the CFM the better. (Cubic Feet per Minute) May also be expressed as Cubic Meters per Minute.

Air Flow is king, any restrictions kill the king. If the backside of your case has a wall 2 inches from it, that is a mild restriction (backpressure). Even so simple as a curved piece of cardboard can deflect the angle to allow a teeny tad better movement away from case, and hence a small difference. Those little differences add up to huge temp issues. If there is no where for the air to flow freely, the largest best fans are still going to circulate HOT air, just be faster moving HOT air, lol.

As far as those Ultra Kaze's, I would probably break out the Dremmel and convert as many of those 80's and that lonely 90 over to 120's, if your that determined to keep that server case. Modding that 80? right above the current front panel 120 to a second 120 looks pretty straight forward. Adding a 120 to the upper 5 1/4 drive area is rather simple, and I think there are brackets out there (help here wiser than thee??). back panel above power supply looks like may pop out and be about 120mm size any way. Don't need dust filter for exhaust fans. just use the existing front panel 120 as a template, trace it with marker onto where you can convert. use simple dremmel bits about the size of other holes. Lots of case modders have done it.

And the door screams for some fans, mesh for it can be ordered.

If your sticking to the 80mm sizes (and the solo 90), I would look for higher CFM and to heck with noise issues and try to find any way possible to open as much airflow as possible. Even if I had to McGuyver it.

For the record, I firmly deny EVER bolting cases to desks, walls, or even the time cement LAG bolts were used in a similar tower as yours. I would NEVER EVER do that!! If I were you (cuz I have never done such silliness), bolt through the feet area., toughest part of most server cases. That would be worth the price of a hidden web cam to watch thieves try to figure that one out.

Because I wasn't there coming up with the idea to cut 6 inch squares out of the floor to put in fresh quickrete with L shaped lags put through bottom of case and into the wet quickrete with an entire weekend to set and cure as everything was haphazardly arranged and mysteriously bolted into walls which were just freshly remodeled in next office AFTER someone (NOT MEE)put the smooth end of bolts in the case and the nut end on INSIDE of wall. No never had any ideas like that.

 

[alkemyst]

my case is 3 80's in front and an 80, 60 and power supply opening in the rear.

The case has about 1 foot or more behind it. It's not bolted to anything. The desk has a lip that extends down preventing the case from rolling all the way out without disassembly.

This is an older image. The 60mm fan is right behind the CPU fan.

I could probably dremel out the front to handle two 120mm fans...the rear may be a bit harder to get more than 1.

I will see how this does. If I have to go to a new case I will have to bite the bullet for a couple optical drives.

I like this guy! :twisted:
I hope you didn't do this for yourself but a client, I've done some stupid shit for others but for me? no. Get by my dog and you can have it all.

What he says about airflow can be "quoted for truth". Jamming an antec 900 into a cabinet will cause a hot system as surely as covering it with a plastic trash bag to keep the dust off. I did get a call on this once,,,

Any larger fans you can mod into that case would help but getting fresh air to that cpu fan and exhausted out the case will be your biggest benefit.

 

[Modelworks]

There are workstations made for VFX work that contain a lot of very hot components, things like 4 quad core cpu on one board along with 3 video cards.
The way they cool them is each area is divided from the others so that the video cards are inside their own boxed off area as are cpu, ram and power supply as well as drives.

You could put a divider made out of anything that works, cardboard even to keep the heat from things like video cards being used as intake air for the cpu fan.

Another thing you might consider is ducting the input to the cpu fan so that it can only pull air from outside the case.

 

[alkemyst]

The fans came. I have to install the 80mm ones but they are definitely noticeably more powerful and the noise level is slightly noticeable.

The 120mm KAZE 2000rpm fans helped my temps A LOT...again not much louder if any.

That 60mm fan though is a turbine. It does blow a lot though. I am not going to use it. I can't see how the 32dBA measurement is accurate unless at much farther than 1 meter

update: I did an A/B with the old fans. The CPU fans don't make a difference really. However the 3 80mm upfront are audible now. It's not terrible, but my PC is under a heavy desk and a bit away from me.

Temps are 10C+ better though. Case temps never breaking 50C anymore. Hard drives are reporting cooler temps as well.

My real solution is replacing my air conditioning system. Hopefully they come back with the Florida A/C Energy Star rebate this year on new systems and the installers don't jack up the price to match it (a/c installs are about $1500 more expensive now than before the federal tax credit, it's sad this happens; but supply met demand). Summer in S. Florida is the wrong time to get quotes. So far after rebates/credits for my smallish 1800 sq ft home, they want $4500 out of pocket. My neighbor with my same home paid $2800 no rebates/credits about 2-3 years ago for a 16 seer Rheem, he has to really be pushing it to hit $150 in electric costs now. His a/c bill is <$100 per month with it set at 75 when he is home and 82 when not. I am at 78 at home, 80 when sleeping and 86 out. We have two people and whatever heat energy 4 cats and 2 dogs put off...he is single. We pay $200-300 per month. When it's over 95 or so we never get below 80 in the house. My office needs a return. The hot air is trapped during the away hours. I don't want my pets coming into it when I am not around. Too many wires and valuable things that are fun to chew on.
