The proper method of calculating Power Factor is: PF=Cosine of the phase shift between the Voltage and Current wave forms in degrees. From the article, "Mathematically, Power Factor (PF) is equal to Real Power divided by Apparent Power." Mike says, PF = W/VA Actually, thats not quite what he says, ...

My only gripe with ALL of MikeC's tests is the usage of Pentiums. I don't see that there's a difference. I mean, a psu works for all cpu's anyhow, the rating is all that counts. If they show the rating is accurate, that a 300W runs stably at 300W, what does it matter if it was an Intel or AMD? I th...

Is there a reason to expect 240V.supplies to be a bit (a very tiny bit) more quiet then a 110, with the higher efficency? (with a thermally controlled fan)

AtW

what a hunk of crap to do that. should make a class action suit against them. 50% ??????!!!!!!!!! Yeah, it pretty high, obiviously people with problems are more likely to participate in the thread, so the number probably isn't quite so high as 50% in real life, but there is no doubt a very high fai...

Hi again, ATWindsor, The Reserator 1 Plus is louder in my actual setup (This time I cut the silicone tubs shorter than with the original one, I'm not sure, but this probably has some effect in the perceived sound, and there is a 20% of anticorrosion liquid from Zalman that has a different density t...

On the forum I linked to, the main problem was cracks in the plexi.

Odd. The actual reserator unit hasn't changed at all, apart from the quick release fittings, so I can't see why its muffling properties would have changed. Equally, I can't see why Zalman would change from the Eheim Compact 300 pumps they've used in the past. Maybe there's just been a run of bad pu...

Hmm, interesting, and if you put a bit of tubing inside the radioter, by the intake, to get the water higher up before it mies, I would guess the resulets are even better. But then again, does the new res plus produse such a high sound that this is nescessary?

AtW

In another topic here, someone mentioned that the new reserator plus is more noisy than the old one. And today I saw some linux-mag that runned a reserator without a pump, anyone who has tried this? Do you get reasonbale cooling results? Another alternative is to use an old thermaltake pump i have f...

Thanks for the very informative post Einllel. If I read your experience right, I'd have to conclude that, although a nice case, investing in a p180 seems to be less useful in a setup such as this, compared to a more "normal" setup. As i would guess I wont be needing all those fans anyway, seeing as ...

I'm buildng a new X2-system (the 3800) with a reasonable GPU (something in the 150-200$ range). Theese too are getting cooled by the zalman reserator plus. This is pretty straght forward, but I wonder about the rest of the system, that is HD, PSU and case. I probably will have one undervoltet nexus ...

the res 1 really doesnt leak on people. its real real real rare. I think the fitting was made with a burr in it. The res might not, but the TT sure does, on a hardware-site i use, there was a poll about the bigwater kit (which is the same as the rocket with a diffrent radiator) with hundrerds of pa...

Well, I still want something that doesnt have a 50% chanche of a leak...

ya know, the zalman has a set limit on how hot it will let you machine get. it lets it get quite hot, but loses heat if you push it above a number, in other words, it has a very small swing yet scares you at first. I don't quite understand what you are saying here, can you explain it again? Is it t...

Yeah, I'm also interested in this, I don't know what is the reason for the pump-problem in the first edition, but is it completly removed in th reserator plus? Just one problem less to worry about if thats the case.

AtW

Let me tell you why people bash bigwater: first of all, the fan isn't loud, but its no 17 db, makes an anoying clicking sound or something. But most important, its build-quality is crap. I have it, I'm one of the lucky ones, where the set works properly. In a poll on a norwegian hw-site, 200 owners ...

I missed tha last poll option, for a even longer review Don't get me wrong it was a smashing review, but If I could anything just as I wanted, I would have liked a couple of more pages on the "medium" system.

Great work Devon

i think it really depends on the type of fans and the density of the radiator :) if you're using a below-average 120x1, 120x2 or 120x3 radiator like the black ice series or anything with large gaps between the fins, then high airflow i think is actually beneficial. (for cooling of course, not for n...

Combine the solutions. Use the RAM card for OS/apps and use a laptop HDD completely muffled in an enclosure for storage. I guarantee you this is inaudible. At that level one should be more worried about coil whine or monitor hum/buzz. -Ed Or even better, use a fileserver connected by gig, silent an...

yeh a more powerful pump, or 2 weaker pumps in series. that should give you enough flow. i didn't take out my hard drive cage either for the same reason - unfortunately that left me with the rear exhaust hole as the only option. not fair, is it? :) Again why? The only arguments i have seen in this ...

I didn't have time to read the entire ting, but I'll do later today, but those numbers doesn't seem rigth, the seem to indicate that a flow rate of about 5 l/h gives a 10 c increase in temperature. FOr that to happen you need to output 3500 Watts of heat. AtW Those numbers are litres/minute not lit...

According to my calculations flow should almost never be a problem, but i might be wrong. Even a real flow of 100l/h should be more than enough, so I would guess bad cooling because of low flow is very rare. Blocks will still cool at low flow, but the cooling performance falls off dramatically. See...

I dunno if this hase been posted or not, and I feel that I should ask before I do anything to the sink. The heatsink I have right now has these really fine grooves on the base of the whole heatsink which seem to be very nicely polished. Now everyone had said lap the sink for better temperature, but...

Then Zalman is screwed. CAN YOU SAY THAT AGAIN PLEASE, I CAN'T HEAR YOU OVER THE RATTLING OF THE PUMP IN MY RESERATOR!!! Ahem. I note that they're selling an additive this time round (and not cheaply either, though quietpc.com pretty routinely over-price stuff). Seems odd if they haven't fixed a kn...

Nah, maybe to some extent. But as mentioned in several threads, depending on how loud your other components are and your ambient noise levels, you might hear a the reserator resonating, it gets very quiet with something soft under it though so removing the pumop might not be neccesary. The included...

Do what i did, mount the pump externally and do it from the start. That way it is much easier to replace it if it isnt enough. Though i think it will be. Also add a piece of tubing like i did, check the link Slaugh was kind enough to post, or click my signature :) I must admit I'm abit sceptical to...

Ah, i love it. And 2.5 liter reservoir. Thats enought to run 50 watts over spec for 35 minutes straight! THe reserator is very cool. I hope the will relase a nb-cooler too, (and a watercoolde PSU )

AtW

I would say it's probably sufficient to cool both PCs as long as you don't overclock them. You're going to need more tubing as the previous post mentioned, and you're probably going to need a bigger pump like the Eheim 1048 mounted externally, as the added resistance of more tubing and an additiona...

Difficult to say, the cooling power of the reserator is determined by the radiator, and how much can it take? I recently picture of a system where a reserator cooled nb, cpu, 2*6800 ultra and a PSU. So i would think you are fine-cooling-power-wise. (especially if ou don't run everything at 100% all ...
