Zalman Reserator1 V2 - any good?

I screwed up with the fan choice for the sake of asthetics.

All 3 fans on each rad are soldered together to run off one header on my fan controller.

The controller was chosen because it can deffo handle the load but it needs more than 7v to start them once they've stopped and clearly I either have 3 or nothing where I agree 1 would be enough to shed enough heat to keep it happy.

Oh well, I will chase the bling!
 
early 30s idle.. not tested load.

And yes, 7 slow moving yates to 1 fast moving yate on the back has made a huge difference!
 
if you look at my build log under my sig the roof mounted 120.3 is the cpu one so it's fed with hot air which probably makes the idle a little higher than some.

Still, the house is probably quite warm too, I can't really move at the moment so Im not staying warm so I need the house to do it for me.

would be interesting to see load difference, but if the temp difference between fans and low fans is not that noticeable then - awesome!
 
running the maximum heat prime on all 4 cores and its settled at about 58 just rising now to 60 I'll run it for 10 minutes then whack the fans on full and see how far down it can go.

worth adding my G0 Q6600 is rubbish, it's got 1.5v in it for 3.4ghz.
 
interesting.
my QX9650 @ 3.6GHz idle is around 33C on air. so I am guessing that on water it will be in the 20s? Priming for 30mins gives a temp of around 60C, so I have no idea what temp on water that would give??

These 45nm cpus are generally cooler though aren't they? So I am guessing that my temps could be better than your's even with my modest overclock?

no there's no guarantee you'd be in the 20s. Idle temps often have little difference because its as much to do with the ambient temp as it is with the cooling power of the hardware (assuming the hardware is reasonably capable like a reasonable watercooler or a half decent aftermarket air cooler)

Its load where the difference lies and even then the difference might not be as dramatic as you'd think, especially with these 45nm chips where heat doesn't really appear to be an issue.

And yes its worth remembering I have more voltage than is generally regarded as safe for 45nm going into my 65nm.

Its been 15 minutes at full pelt now and its 65/65/62/62
 
ok that was half an hour and it bluescreened but I'm sure thats because my clock is slightly unstable rather than the temps, half an hour at 100% across all 4 cores is much more than it normally ever gets.

Temps had settled at 68-70 across core 1 and 2 and 64-66 across 3 and 4.

Fans on full whack now to get rid of the heat and I'll start it again shortly.
 
2.4

As for idle temps, Intel CPUs put out almost no heat when idle so you can't expect water-cooling to make any difference to your idle temps. You can expect to need no fans running on the rad when idle though or under very light load such as downloading over night or watching a movie.

Even at full load, if it's for short (<10 minutes) you won't need active cooling. If you're running at full load for extended periods (24/7 for example) you will need pretty constant active cooling but nothing like what you would need with a standard heatsink.
 
ok, fans full tilt.. all cooled down (had a little snooze lol) currently 34/32/30/31.

And... GO! (for half an hour max!)
 
20 minutes and its 55/55/50/50 so there's a fair old difference and its not exactly what I'd call loud but you do notice when you turn the fans off.

Being 12cm yates the noise is nowhere near as nasty as a stock gfx card fan.

Still, that was never the point having it on 100% load, games never get 4 cores to 100% load so I might have a go at passive and see how often/it ever restarts.

Mind you, to give some relevance to this thread, its a good £300+ worth of watercooling gear in my pc. There's £120 worth of rads!

EDIT: after 40 minutes-ish 55/55/50/50 so yes a lot of difference but still, they're going off now lol!
