What a difference 7cfm makes!

[MichaelD]

This is one of those "feel good" threads.


55C to 49C in one, easy, 10-minute operation.


I run an OCed XP2100 B TBred (who doesn't?) anyway; I have an AX-7 on it with AS3. I was using a Vantec Stealth fan which is rated at 27cfm @ 2100 rpm. Very quiet fan.

Running P95 TT for an hour shot my CPU temp up to 55C. That temp is partially due to the fact that I have my cases' exhaust fans thermally controlled by the Antec Trupower PS (very quiet!).

55C is a little too warm for my tastes. So, I swapped out the HS's Vantec for an Antec BB fan, which is rated at 34cfm @ 2600 rpm.

A 6C drop, and the noise is very slightly louder...you can hear the higher speed fan a little, but it's very muffled b/c it's buried inside the case.

I'm happy.

That's SIX degrees Celcius, people.

 

[wfbberzerker]

SIX?! why didnt you say so!

 

[MichaelD]

Hooray!!!!

I never hear much about Antec fans in here but that's about all I use now and I have no complaints. Actually, I went to a 92mm Antec for my SLK800. Quieter than the 80, which wasn't too bad to begin with. The 92 is nearly silent.

My CPU has reached 71c and its ran (Running F@H 24/7 in a hot room)

Man the stock Athlon XP2100+ cooling doesnt cool for jack

Antec makes some nice fans...I have learned thru experience that unless you undervolt things, all fans make some nosie...no such thing as a "silent fan."

I have some Antec BB fans that have been in multiple cases for a few years and they run just dandy. Antec rocks; all their products that I have bought/used have performed admirably and w/o complaint.

YIKEEEES! :Q :Q

And i thought my 51C was bad after an hours full load on my AXP 1800 Tbred A :Q

DannyBoy, was your 1800 OC'd?

Not originally.

I overclock it here and there, but im still using SDRAM and i cant oc my memory too much. Seeing as the K7S5A only supports FSB oc's if i oc my processor, i oc my memory. I dont want to fry my memory because i will still have use for it when i switch to DDR

Why you ask anyway Mike?

i'm gonna stick a fan in front of my harddrives. i've decided they actually put out more heat than the processor. taped a meat thermometer against one of them and its running 105 F, or about 40.5 C. the amount of heat produced might be ok except i have 3 drives.

Not true my Fan is completely silent, hell it doesn't even move.

I have a 120mm Fan infront of them tucked away. Its my intake fan as well, so kills 2 birds with one stone....in a way .

My 2 hard drives used to be about 40-45C and now im lucky if they jump 30-35C.

Keeps me happy :beer:

How on earth do you expect it to make noise without it moving

i don't think 6 degrees is worth more noise unless your crashing. cpu's aren't worth squat, esp over time. if it burns in two years who gives a %#@.

I don't think that his noise level went up much, if any, though.

And remember, that's YOUR opinion. You noise freaks are crazy. I can't sleep without the low hum of my computer. Of course if I turn up all of the fans my case gets a little louder, but it's not unbearable. 6C is a pretty big difference. And if you haven't heard a PC Power & Cooling Silencer fan, then you don't know what silent is. Those things are DEAD silent IMO. I can hear them if I put my ear right next to them, but inside a case (even if it's right next to my head), I can't hear a thing. Not one peep. Truly amazing.

However, I also want to say that the reason for the drastic temp difference might be partly due to the Vantec being over-rated. I have heard that they put out more like 24 cfm. When put up against a PCP&C Silencer, the Silencer (also rated at 27 cfm) filled up a plastic bag faster than the Stealth. If it's true that the Stealth is putting out more like 24 cfm, then going to 34 cfm, you probably increased your airflow ~42%. That's a HUGE increase, especially when 24 cfm isn't nearly enough air to push against a heatsink to remove heat.

well, those stealth fans aren't that silent. i have a few myself. i dialed my 92mm intake stealth back a little with my fanbus. but with a few turns of knobs on the fanbus i can create a monsterous sound. have both the powersupply fans(antec) connnected to the fanbus. apparently antec runs their thermal control powersupply fans at about 50% most of the time as their max ever. cuz when i run the powersupply fans at max, my pc sounds like a dustbuster. its quite insane. i mean off the scale. i've had 6800rpm cpu coolers before, so i know what normal loud is, its still nothing compared to rewired antec powersuppy.

next time i go 120mm.

 

[MichaelD]

The Vantec fans are overrated; I can tell you that. They are quieter than standard Antec fans, but they aren't silent.

They did make a diff when I had four case fans...my noise level dropped by 3db as measured with a SPL meter (yes, I own one...bought it for the HT, but it comes in handy elsewhere too.)

I ran P95 TT overnight (11 hours and change) and my CPU temp was 49C. With the Vantec fan it would've been 55C.

My case is almost imperceptibly louder...from a few feet away you still can't hear the case, but up close, there's a low-pitched hum type fan noise...very muffled by the case itself.

I know that CPU aren't worth squat, but who wants to buy a new one before it's time? Admittedly, I am pretty much overclocking the snot out that CPU. 200FSB. :Q Programs are decidedly more snappy now.

 

[0roo0roo]

edited my post. antec powersupply fans seem to run at 50% max, cuz i wired mine to the fanbus and at max they are dustbuster level noisemakers.


my thing is to install a few 92mm+ fans and run em slow. high pitched noise is more annoying then low pitched noise any day.

Agreed. I wish I could fit 120mm fans front and back in my case. That's what my box at work has; you can't hear the damn thing at all.

i just cut holes in the sides heh

Never gets above 35C (and man is it quiet compared to the Volcano 6cu which was cooling the previous CPU - Athlon 850). Looks cool too.

Just wish I could overclock more on this K7S5A board. Maybe after I update the BIOS...
Problem is I don't see an option to up the FSB beyond 133 in the BIOS. I suppose I need to read a o'cing article?

Oh and gratz michael

Antec r0><0r5 y0ur b0><0r5

 

[Whitedog]

What does the 2100+ XP's overclock to? I'm still running an old 1700+.

I've got a new mobo, an A7N8x 'lux running dual PC2700. Do you just crank the FSB up to 166(333)?

 

[Whitedog]

Let me guess... it's the 2100+ T-Bred's that overclocks well? Any particular model/stepping? I've got pricewatch up, I'm going to just order one and get it over with...
