Zalman Alcu 7000A w/ Athlon 64 3500+ ?

I've recently been overhauling my computer - virtually everything new except my cooler, PSU and hardisk. I originally used my Zalman Alcu 7000A with my Athlon XP 2000+. Now I've migrated to an Athlon 64 3500+ and installed my old Zalman on it. Originally, the cooler was listed to work up to 3200 speeds (whether or not this was with 64 bit architecture I do not know). On Quietpc.com now, it says it is safe up to theorectical maximum of 4GHz (okay, with the 7000B model, but the A and B models are virtually the same AFAIK).

So, am I safe running the 3500 CPU with this cooler? I usually leave it in 'silent' mode too, although I probably would turn it up if playing a demanding game.

What sort of temperatures should I look for if there's no straight answer?

my brother has a zalman 7000b alcu on a 3200+ venice oc'd to 2.4ghz (3800+ speed) on stock voltage. temps never exceed 50c with the fan on low (ambient 24c/75f). i'm not sure if there is a difference between the A and B version of that cooler. hope this helps.

That upper limit you mention is for an Athlon XP 3200+, which is a very hot chip indeed. I have no figures handy, but a Barton definitely puts out more heat than a A64 of similar speed ratings. You should be fine... for my Barton, I keep an upper limit of ~65C under max load. For an A64 I think you would be hard-pressed to reach that temperature with a fanned heatsink, even the stock one.

Just run CPUburn or similar and watch your temps. I'll venture a guess and predict the core temp won't exceed 55C... but the proof is in the eating: try and find out!

Zalman says it's ok to use, even at silent mode.

Cheers,

Thanks for the replies. It seems well enough, been going a week or so now. Haven't run it under a really heavy load yet, but my box is in a cupboard and my motherboard the heatpipe asus. The temp atm is only 42C CPU and 45C motherboard.

I've been using a moded cnps7000, it works far better than I ever expected it to.

Thats an old picture of it in my AXP system, its now in my A64 system. I'm running 289x9 @ ~1.65V (1.6V reported).. Idle temp is 28C, Load temp tops out around 46C. At stock I was getting 25C idle and 34C load.
