A64 Performance

[Keith75]

Sure, two in the front of the case towards the bottom, two in the rear, two in the power supply and one in the side over the processor.

Keith75,

Do you have the computer in your room? Is it noisy?

[Keith75]

Yes, it is in my room. Before I got my new chip and motherboard it was really bad. I had a Volcano 11+ on my 2500 and it was way too noisy. I am now using the stock cooler on the A64 and it is pretty quiet. The case fans run at low speed so they don't cause much noise. I love it. It is probably twice as loud as a regualr case with one or two fans but it isn't the kind of sound that bothers you. Just faint background noise.

For what it's worth:
I have the filters on the air intakes. I can show you pics of those too.
These are really nice filters (cheap too)... the base of the filter screws
in with the mounting of the fan. The mesh lays in a 'tray'. and then
simple cover snaps over it all hiding the screws and making it look
professional. The casing and filter are black so it's very non-offensive.

If you would like, I can post (ASSUMING my dsl is back up) a url
to a pic of the inside... [[ at work right now, waiting for assignment,
and the dsl is being worked on. last word was someone took out
the junction box down the street and snipped major trunks ]]

PLEASE promise not to laugh at how messy it is or how much 'junk'
is in there... the contents are always changing.. LOL

I did forget to mention that I have the cooling fan in the supply. I never
count that as it's primarily to cool the supply. I do have, as a standby,
a fan at the top of the chassis (90mm) and a fan in the front (120mm)
which are also standby. They can be turned on when the A/C fails to
keep things in operation. For extreme emergencies (like cpu cooler
failure... I have a 28mm tornado blower (85+ CFM) aimed right at
the cpu.

So, counting everything (including CPU cooling fan)... I have.

PS fan, 2 exhaust fans, 1 top fan, 1 front fan, and 1 side fan (28),
and CPU cooler fan..... total = 7, with 4 in normal operation; 3 as
standby.

I am considering setting things up so that instead of using just the power supply temp sensor to trigger the turn-on of the emergency fans, I'm thinking about using a simple 2-diode/resistor arrangement that would allow any thermal condition triggered by the MB or PS to turn on the emergency fans. One of these days, I'll just dig the parts out of the
box and solder it up.

My computers are in my room and are quiet. If you turn on the TV or even watch a DVD on the PC, you can't hear a thing UNLESS the Tornado fan is running at max (6500 RPM). The T-Take fans are silent at full speed ****IF**** you cut out the grill work (drilled holes) on the back of the case... That's the trick there... zero air flow resistance outbound.


Let me know what pictures you all would like to see (if any) and I will shoot & post.

Keith & all,

I dug into the Thermal-take site.... and found the VENUS series.

That is what I use.. Also take into consideration that I use Artic Silver 5 (which is WAY better than their other products, but does take up to 200 hours to 'cure'. more info about AS-5 on their site).

My specific cooler looks like the A1838, but is taller w/ red-orange color fan blades. I want to say A8901 or A8801.... I will find the package and let you know.

I do know my package said Silent Boost K8+ or something like that... there was a DEFINATE indication of it being more than the norm..... PLUS my fan blades are red/orange... not black. It is definately silent at full speed though!!!

I also found a matching K7 series... but again, no 'red/orange' blades or the 'plus' designation... I know it's there somewhere.


Sorry for forgetting this in the previous post, just found the info now.

As I said earlier today, I have a 120 mm fan on the front side of the
chassis.

From my experience, SUNON makes an excellent 12v, ball bearing, low rpm, high volume fan, and QUIET for the price.... Here is the link to the Sunon site for you to see and evaluate.

http://www.sunon.com.tw/products/pdf/dc-fan/general.pdf
(page 8 of this pdf explains how they encode their product numbers)

The only thing NOT listed in this link is the complete KDE series, just the older products.

In the Sunon line, like everyone else, they have 3 basic types for PCs.... the MOST important part of the number is the last digit before the '-'

If you have a case with a restricted / difficult air flow path, you will want a fan capable of the higher pressure to 'blow by' (or 'suck by') what's in its way.

I use both the 'B1-' and 'B3-' series fans depending on the case air flow and amount of PCI cards & disks it's trying to blow through -OR- if it is simply an exhaust fan. I tend to use the higher pressure fans when blowing in (since I am pulling through a filter) and the lower pressure fans for exhaust (where there are NO obstructions).

Cases are usually designed for 30mm or 40mm of space between the front face and the drive... this is what we have to work with.

Most of the deeper (20 inch) cases have JUST enough room for the 38mm fans. the fit is tight. Best technique is to do this before drives are mounted and then insert the fan through the drive mount area. The 25mm fans will slide in the side with drives already mounted.

In either case... once you have mounted the fan and filter/grill... seal off all air leakage around the fan and surrounding framework for inlet fans.


I have a Sunon, KDE1212PMB3-6A... This one runs at a 2400 RPM, 35 dBA noise level, 120x120x38 , and 84 CFM. This is a typical exhaust fan.

My other fans are the KD series... B1 fans @ similar speed, noise, higher pressure, lower volume (that's the trade off) and are primarily INPUT fans.


I'm not trying to turn this into rocket science as it sure looks.... just share what I have used in various case designs, given the the amount of heat...(some cases have 2 power supplies).

Like any fan, larger size usually means lower RPM at same or more CFM, but you sometimes lose pressure.



My master rule is to Pressurize the case through filtered air first.... then exhaust it where I want. That has never failed. Just remember to push in a little more air than you are going to pull out and all will be fine.

One example I can give (US Postal Service) is the original Athlon 1200MP (A4 and A6) was safe to operate up to 122F. My customer required an ambient air temp of 100-110F. That gave me only 10F to use to cool EVERYTHING, knowing that air cooling is usually in the 15F range across the heatsink alone, I made up the difference in volume. The result was a 118-120F max CPU temp and none of them have failed yet.


Hope this helps. Given the new processors and the time it will take for the everyone to learn how to cool them, *WE* have to deal with it....
So, here is one of the things in my bag of tricks.

BC,

Each time you write here is a lesson to me. Thanks teacher.

[BC]

Thank you and you (EVERYONE) is welcome to anything I know. I don't get much feedback other than 'you talk too much' ... LOL.



To be totally candid, I have always wanted to teach.

When I saw that todays graduates are highly skilled in certain areas and concepts I have trouble grasping at first, almost all of them lack the basics of 'how does it work inside the computer'. Ask what to do when the program runs slow? The answer you get is " Buy a faster processor, bigger disk, or more ram." In my opinion, although the techniques of software development and the things we are capable of have grown exponentially in magnitude, the knowledge of how the electronics work has fallen at a similar rate.

If this continues, the art of building a machine will soon be lost. only those of us who play with it all the time will be left. What's worse, only us "Dinosaurs" remember how to keep those old monsters cool...

It's time to pass the knowledge.... Time for the next generation to take what we know and build on it.... make it better.... that is my wish / goal / desire.

To finish this little comment, as soon as I can complete my teaching credentials, I will teach. I have been extended an open invitation to Dartmouth, as well as a few other good schools.

Question is: Should I stay here and advance the science, or step over to the academic world and reseed the knowledge.

I ask you.... Given what you have seen since I joined a few days ago, would you sign up for my classes at a University???

** EDIT ** "..... Or run the other direction??? lol *END EDIT

Try to write in a simple way.

If you have passion when teaching just go for it.

No because I'm getting here free lessons!

[WienerDog]

ya BC rock on
heh i know just enuff about computers that i can mess one up really fast :roll: so i read and try to learn. and its nice to have some one just "talk too much" rather than talk down. =D>
