Can I use a SVC GC68 to cool a non OC 1.4 TBird 200FSB CPU?

Hi,

I'm upgrading an older pc with a 1.4 TBird 200 FSB CPU from a Duron 750. I have a SVC GC68 that I was going to use on the Duron and I'm wondering if it would be enough cooling for the 1.4 TBird? I know that I can use it up to a XP1800+, but I had heard that the Tbird's run hotter.

What do you think?

TIA,

Sal
 
I don't see why not.
I'm using one on a 1.0ghz Tbird, and it's running fine. Never had it on a 1.4ghz Tbird though.
 
Thanks for the info! Ok.. Now that we have it established that I can use the GC68 with the stock fan on the Tbird 1.4, can I possibly use a Panaflo L1a or similar fan with the GC68 or should I stick with the stock fan?

Thanks again!

i currently run a tbird 1.4 with a gc68. i originally had the panaflo L1a on there, but later decided the cpu was running hotter than to my liking, so i put the stock fan back on. i didn't notice much of an overall noise difference, as the stock fan is actually pretty decent.

hope this helps.

been there, done that ...........

currently using a tbird 1GHz with a GC68 / arctic silver 3, epox 8k3a+ motherboard

according to speedfan, case temp. = 32 (with 1 antec case fan blowing out, 1 panaflo L1A blowing in/cooling the hard-drive), and an antec smartpower 330 PSU with a 92mm sucking air in, and a panadlo L1A (my mod). exhausting air out.

* vantex stealth 80mm (max. temps. under load = 44 C, steady state temp= 40) 2100 rpm
* also tried a panaflo L1A (very slightly quieter, ..steady state load 42) 2000 rpm
* stock fan, 37 - 39 steady state, but quite a bit noisier, although not as loud as stock - 2500 rpm approx
* also tried a variable speed fan (max. temp under load, 39 C, steady state max = 37 C) - 3000 - 3500 rpm, ..... and much cooler if i turned up the rpm to unreasonable levels.
* stock athlon 60mm cooler, 42 C (steady state) - 5000 - 6000 rpm -(though i'm not sure about the rpm)

keep in mind that you can't compare a 1.3GHz T-bird to a 2000XP, ... the XP's are different core and in general generate less heat than the faster T-birds (the 1.3 GHz was especially guilty in this regard)

To answer your question, i think you can use the T-bird with a GC68, but only with the stock fan or a faster variable speed fan (suggested), ...in either case, the gc68 is better than the stock cooler

Ok guys.. Thanks so much for the info! I can use the GC68 on the Tbird 1.4, but only if I use the stock fan or something that cools better. Got it!

Thanks again!

Is there a 80 mm fan that puts out about the same CFM as the stock GC68 fan, but is less whiney? This fan is a lot whinier than I thought it would be considering that it's a 80 mm fan. I don't mind air noise, but I hate the whine.

BTW.. I'm getting about 43-44 degrees celsius temps at idle in the BIOS for a non oc Tbird 1.4 ghz 200 FSB with the GC68 and stock fan. Where are you guys getting your temp readings? BIOS?

Also.. What would be too hot for this chip? I wouldn't mind if the chip ran a little hot if I could use a quieter fan like a PC Power and Cooling Silencer or Panaflo L1a.

TIA,

Sal

for the past 6 months I've ran a 1.4 ghz tbird with a Vantac 80mm stealth fan, it's pretty dang quiet. My idel temp is 45 degrees, under load I hit 48, it's a very close range. This is with AS3 applied as well, but the temps seem good enough to me quite honestly
 
Yes you can, but remember, LAP THAT PUPPY!

How much of a difference am I really going to see if I lap the hs? I've heard that it's very minimal. Maybe 1-2 degree's celsius. Of course, the hs on the GC68 is pretty rough to start with.

For those of you that have lapped the GC68, how much of an improvement have you seen?

Also.. If I decide to go with a higher cfm fan like the stock GC68 fan, does anyone know of a fan that is less whiny? I don't care about an air type noise, but I hate whines like on the stock AMD 60 mm fans. This fan sounds just like it to me, but a bit muted is all by comparision.

Thanks again.

I'm going to be the stubborn one and say to get a better heatsink. My evaluation of my GC68 with three different 80mm fans (stock, NMB low-flow and Panaflo L1A) convinced me it's best suited to Durons or low-end AthlonXP's.

The heatsink itself doesn't seem to be too bad... it has a fair amount of surface area. But a lot of the airflow from an 80mm fan just skims the edges of the heatsink. With a smaller fan, or a fan that managed to put more airflow through the center area (TDM, for instance), it would have more potential.

The 1.4GHz Tbird puts out a higher "typical power" than an AthlonXP 2700+, as you can see from Sandpile.org Anyone going to recommend the GC68 for a 2700+...? Didn't think so. 😉 Oh wait, I see a hand... 😀 (I guess we didn't put the straitjacket on tight enough 😉) My recommendation would be a Thermalright SK-7, which also has a copper base that makes it suitable for Thoroughbred-based CPUs if/when you upgrade. Got one on order myself... 😀
 
I just installed the Vantec 80 mm fan instead of the stock GC68 fan. Temps are only about 3-4 degrees Celsius higher. I need a good way to guage the temps on my cpu. I tried MBM a couple of times and I can't seem to get it to work. What pisses me off more is now that I've installed MBM and then uninstalled it, I can't get the temp readings from Sandra (even though I know they are high). At least I could see if the temps were going up. That's where I got the 3-4 Celsius difference reading.

When Sandra could give me a reading, my temps were about 54 Celsius with the stock fan on the GC68. With the Vantec 80 mm fan, the temps were 57-58 Celsius. While my BIOS was telling me that temps were around 41 Celsius for the GC68 and Vantec fan combo and 39 with the stock fan on the GC68.

What temp readings would you believe? Since I can't get MBM to work, I don't know what to use.

Oh.. Another thing.. Because I can't get a good temp reading I decided to put the stock fan back on the GC68 for now. I noticed that a major source for my system noise is coming from the power supply fan, so it really doesn't make that much of a difference for me to use a quieter cpu fan at this point. I do notice the difference between the stock fan on the GC68 and the Vantec Stealth, but the noise difference just isn't worth it right now until I address the PS fan.

Thanks again.

Running stock GC68 with Athlon Tberd 1.4GHz @1.5GHz, hovering around 50C at idle. 100% CPU makes it around 55C max.
