also in this thread it it has not been about money....

I never mentioned money once.
I have a familyand work hard for a living..The fact is that you get what you pay for. nost of the time.

actually I have raised a family and such and now that I have grandkids....its all about money...

Yet I havealways believed if you must ask how much something costs then possibly you ought not be getting it...
Sure I look at several sites before I buy...

Yet you`ll never hear me saying anything about the cost of something...unless its a comment as such..

Mainly becuase I believe a company has a right to charge a fair and equitable price so as to not go out of buisness!!
At the saame time as a consumer we all have a right to shop and buy where we deisire...

Have a good day!!

Wthout being ripped off.

Of course there are eveptions...there is the brand factor.. a lot of vendors take the the same product dressed up and they seell the the sae thing at different prices..ASUS gpu's come to mind.




I will probably put a Panaflow 120mm L1A -- 69cfm 30dB(A on this Si 120 . Should be ok withh that.

ASUS GPU`s......

Actually I read somewhere that ASUS usually getsa the pick of the NVidia Chips for there video cards....for a price though...

I was not aware and still am not aware of another company making ASUS GPu`s for ASUS??

Enlighten me....website plz?

Because most ASUS GPU`s rock big time!!

Well since I have an Asus N7800 GeForce GTX TOP Edition to install in the rig I am building I came across this review/article the other day.
http://www.gamepc.com/labs/view_content.asp?id=asustop&page=1 this is true with a lot of other stuff as well..eg. some ram from OCZ, Cosair and Mushin even Crucial are idential exept the price.
Nec and liteon DVD witers are the same but for the price...
Shall I go on..

Here is the current profile -- keeping up with material I've posted over the last week on other threads -- for a Prescott 3.2E @ 3.5, Ext. Freq.= 250 Mhz, FSB=1,000 Mhz, memory @ 500 Mhz DDR.

The system is cooled by an SI-120. The Mosfets and PLLs have been sinked as thoroughly as possible. There is a motherboard duct supported by in excess of 100 CFM from the front-intake @ 1,700 rpm each, about 80CFM at idle for the CPU-Fan with speed-range 1,900 to 2,900 rpm, and exhaust of approximately 100 CFM from two 92mm fans running at 2,800 rpm each.

The room temperature is: 70F

CPU Idle 90F/91F
CPU Load 101F
Mobo Idle 79F
Mobo Load 84F

VGA heatsink temperature sensor, load, 97.7F
Chipset heatsink temperature sensor, load, 92.3F
Memory heat-spreader sensor, load, 98.6F

VGA nVidia sensor, load, 104F

All load values measured under PRIME95 "Large FFT" torture-test.

The Artic Silver 5 is approximately: 10 days old.

I rest my case....ASUS has always made there own cards.....just becuase they look outwardly identical in the past doesn`t mean the cards are all made from one and the same company....

Have fun...nice link though!

I have at present the XP120 in my system! Again another 3.2 EE also with 1024 megs DDR 3500 memory!!

I am currently using a Thermaltake Smart fan on my CPU 1300rpm aprox 40cfm at 17dba
max rpm 2800 - 84cfm at 46dba.....

I saw no difference at all in my temps when I mildly over clocked my CPU up to 3.6mhz.
I have had my CPU Overclocked upto 4.0 steady running prime95.
I have3 taken my CPU to 4.2 but it was not stable for very long!!
Also the temps at 4.0 were not that high in fact compared to the temps I was getting using the stock Intel approved hsf and fan you could say my temps were pretty low even at load!

XP120

Ambient room temps did not fluctuate more than 67f to 74 f!!
idle--27c under load for 12 hrs-- approx 42 and that is on the high end....in all probability it was probably under 40c
overclocked nearly the same temps increased marginally!

I am running coolermaster LED fans on both my intake and exhaust speed 1220rpm noise 22dba and cfm 42.7.

I am also running a zalman intake on my side panel 1700-3000rpm with 20--34 dba and airflow from 20--36cfm!

Thes temps even under load were taken with all my fans set to there lowest RPM via the Zalman Speed fan Controller....

I also have a salman slim fan inside the case blowing air on the memory!!

My case is dead silent unless I am gaming and have everything turned all the way up!!

The only fan I can hear is the Thermaltake Smart fan and just barely turned all the way down!!:laugh:

For either throughput or certain types of noise, I could've done better than choose the EverCool 120mm aluminum fans for the front intake. They are quiet below 2,000 rpms; above 2,000, in addition to an increase in air-turbulence (which you get anyway), the bearings begin to rattle. You have to focus your attention to hear it, but it's "there." Those fans are tuned down to 1,700 rpm. Not such a problem, since their combined throughput is double. The fans top out at 2,250, providing about 82 CFM at that speed. What with filtering and the lower speed, I figure they're good for a combined CFM of at least 100.

The CPU-fan is a Delta Tri-Blade 120x38mm

Notice the noise rating -- above 50 dBA. That's the noise you can expect at 3,700 rpm. But the fan is set to run between 1,900 and 2,900 rpm, and there is no noticeable motor-whine at those ends of my chosen range.

I'd probably recommend -- given what I've learned in the last two months -- choosing a Panaflo -- probably the H1 fan with the TACH monitoring. It's just a tad quieter -- about the same -- but you don't need your fan to rev at 3,700 rpm, anyway.

The rear exhaust 92's are ThermalTake 92mm BLUE LED "smart" fans. I don't care if they're smart -- I run them off a controller at about 2,800 rpm. They spin up to 3,600, and I was fortunate to get a sample of them that don't have much motor whine at that speed, leaving only air-turbulence. But I don't need to run them above 3,000, anyway.

The choice of 92's for the rear was given by the rear-chassis design that didn't make it "easy" to install a 120mm fan. A more recent "experiment" I made with a 1996 Gateway full-tower proved to me that you CAN install 120mm fans in rear-chassis with these "difficult and irregular" surfaces, and I wish I had done so with this case, but the 92s produce enough CFM that the motherboard duct never spews warm air into "cooler" parts of the case.

As for the Delta, between a Panaflo I ordered without TACH monitoring and several other fan (including the TT 120mm BLUE LED 120 and the Silverstone 120mm fans), this . . . is . . . "THE ONE." But it could just as easily be a Panaflo with TACH monitoring . . .

Also -- Even for a full-tower case -- I don't think two 120's in front are really necessary. The CPU fan could spin at 1,500 at idle and the SI-120 would still cool effectively. With that, I could get by just fine with a single 120 in front spinning -- at its fastest -- 2,500 rpm -- probably less.

BonzaiDuck ,
That is an awesome Delta fan..

I am thinkinking about Pannaflo 120's Front and back and heat sink ..& 2x Acoustica 120's for ram and wherever.

If the Panaflow's can be controlled. I might need an exhaust blower ...
There an Artic N V 5 rev 5 on the vid..card.

All Panaflos can be controlled; not all Panaflos have TACH monitoring, just as not all Delta and Sunon fans have TACH monitoring.

Yeh,
the 92mmm 's have TACH monitoring but no 120 has...but I think i can be done!


*** need to find a h/p quiet 120mm.

Any suggestions.
Or go with XP-90c and Panaflow 92m with TACH monitoring! NO.

zest this is your thread so the topic can move around your questions,one would suppose.

The nine blades that the Silverstone fan offers looks good but the mm of H2O pulled does not. I'd love to talk to my Uncle about this but he is very ill. He did fan design at Babcox&Wilcox for 40 years.

The Delta BD linked does move more air and has a higher dB but i would think if it was undervolted to the cfm of the Silverstone it would still be a little louder but pull more mm of H2O.

Specing a fan's cfm in free air is one thing but putting a fan to work in a PC enviroment
where it has to pull through grills/air filters and drive air between HS fins is another.

Check the mm of H2O pulled on both these fans. That is one spec that is near the top in my mind when fan shopping. I'm not saying the SS is less-than just that it's application would seem to be limited to free air use, ie.very little resistance to movement of air.
The fans that are better at moving acceptable cfm with good static pressue and doing so with low dB are generally 38mm wide.

I am definetely putting a Panaflow on the heatsink ..69cfm 30dB(A) Should do.

Q: 120mmc ase fans front & rear.. what kind of power/airflow (cfm ) is genereraly equired! And should both be the same.
Sorry if this is a kinda daft question .

Intel.

Intel=hot & i will try my hand at OCing mine(2.8)

Only from what i have read here at AnandTech, after 130cfm of intake the law of diminishing returns will make it's presents known on a mid-tower.
With the case that i'm setting up right now.
114cfm intake, about 100cfm exhaust..That's with eveything maxed out. There is a Sunbeam Rheobus in place to slow things down for 95% of my PC use.
After cleaning out the opticals, a slight positive case pressure is what i'll prefer.
Negative case pressure will pull extra dust through all the little cracks.

A 92x38 is at the rear, a 80x25 is directed right at the intake of the PSU and it has an aggresive 80mm fan of its own, the intake is a 120x38 Pan.

A deflecter will be used to direct 65%+ of the intake air up to the HSF area. Nothing sits in front of the intake fan to defeat it's intended purpose. I relocated the HDD cage.

Why not get a thermaltake big typhoon, it has better cooling capabilities than whats been mentioned, from what i've read and heard anyway.

That is THE one...think you are spot on there buddy.
Mogadon: Why not get a thermaltake big typhoon, it has better cooling capabilities than whats been mentioned, from what i've read and heard anyway.
TOO loud.
The objective is to get MAX system coolong with lthe least abount of noise..I think I would get Zalman CM9500 if was going for something like that .

actually I have been reading many reviews by people who have bought the TT Big Typhoon and alot of them have 2 issues with the Typhoon...

The first being you need to take your mobo out to install it.

The second being they are not getting the drop in temps that the felt they should be getting.

As is the case with computers.....different heatsinks work better for different computers!!
