I am very reluctant to add any fan. I went through a lot of trouble to remove all fans. I am not looking forward to put one back. Yeah, it's your call. But trust me, nowadays there exists fans that can not be heard when installed inside a case and undervolted, unless you are living inside an anecho...

My question: will my zalman gpu block fit on the X1900XTX ? Will it be sufficient to cool the whole card ? I do not have any first-hand experience of the current-generation graphics cards, but as I have succesfully cooled my Athlon64 3500+ / X800XT rig with Reserator I for 15 months now, here comes...

Thanks a lot for a hint!

just make sure your radiator isnt copper, or you risk turning your entire cooling system into a battery that will literally disolve your rad and waterblocks Not exactly. To get real battery effect you need to have electrical current in both ends and some potential difference. Yes, mixing metals wil...

I don't think orientation of the MB makes any difference. Water will anyway be forced through the loop and tower is external. So I'd stick with Zalman's instructions and contruct the loop like reserator -> flowmeter -> cpu -> gpu -> reserator. In the end is does not matter so much what order you pla...

Quad TEC system: http://zds.iki.fi/zds/projectlog/images/freezeone_calc_1.png Voltage fed: 2.8V Power usage of TECs: 3.9W CoP: 5.898 Oops. As the image shows, the 3.9W is for *single* module, so all the modules together eat 15.6W. Voltage and CoP were correct. Anyway, the main point was that you ca...

To be a bit more verbose: Heatpumps with high CoP (coefficient of performance) can be really useful for silencing people, if used properly. What this means in practice is that if you are going to employ TECs, you should carefully engineer you configuration beforehand to ensure that the system really...

It depends on how you use them. See my analysis in this thread.

As in so many projects, once you dig deep into it, you begin to add more and more things to it. Making use of the thermoelectric coolers (TEC) was first just a crazy idea, but has since become integral part of the project. Earlier this week I ran into very interesting article article in Electronics ...

One part of their FAQ jumps out as being simple, total BS: " Do CoolIT systems require power supplies with greater than normal capacities? No. While the TECs do use power under heavy load, the system reduces power consumption at the die level due to lower operating temperatures. " That my friends, ...

er that's some sick temperatures. you need some heat dood. I should chop some wood for you! :D No thanks, I'm already sweating at 22C, but my girlfriend tends to feel cold in all temperatures below 28, so we had set temps to stay at 22.. So maybe you could buy her another sweater, instead of the wo...

And yes, I have my Reserator tower behind my case as tjpark1111 suggested, so that PSU and case fans provide it some airflow. Now that it's -19,5°C outside I also noted another thing that might affect my overall temps: My Reserator is against an outer wall and beneath a window, so ambient temps fo...

To me it's very peculiar that you guys don't seem to hear a fan spinning over 500 rpm, not to mention if on a rad, where the fins add to the noise even if they are not as tightly set as on my Black Ice. My understanding is that fins add _more_ noise if they are tightly packed. This is the same as i...

But a 5 V YL fan on a rad makes more noise alone than a whole computer made around Nexus fans, state of the art air heatsinks and active fan control. I seriously doubt this. I also seriously doubt it's possible in normal room ambient noise level to hear 5v YL fan on rad at all, so the point is pret...

I did some math on this; I am not a physicist, so if you are, please correct me :). So if I have understood it correctly, in system like this the higher CPU heat output works *twice* to increase the seen CPU die temp. So, the cooler running AMD system produces H amount of heat and CPU is running on ...

are they really? If you check the sound files on this site http://www.cooling-masters.com/articles-33-14.html (also mentioned in older post with explanation) , you see that one cannot take that for granted. I wish it was true though.I could use the extra space. Remember that those sound files were ...

I think the point was that instead running D5 at setting 1 you could get DCC or CSP-MAG, that are quiet even at full throttle.

I have unluckily no first-hand experience, but I'd seriously consider Lian-Li. People have built some pretty awesome WC systems inside Lian-Li cases: http://franklin.noph33r.com/images/overzicht5.jpg http://pic18.picturetrail.com/VOL932/717679/5462051/89477836.jpg http://photobucket.com/albums/v281/...

Doug G, HPPS is quiet alright but it produces a humming throughout my case that disappears when I close it. This sounds like a vibration-induced noise. How have you mounted your pump? And remember that there seems to be quite a lot sample variance in the pumps; for almost all of these pumps there i...

Umm, so you think it's more likely my sensor is wrong, and not his who was getting 36 C? Is it more likely for Intel to be wrong than AMD? Has someone studied this? I really hope Intel is wrong, because my next processor will definitely be AMD. I didn't mean to imply which of them is wrong. Both of...

I was just wondering how it can even be possible to hit 36 C at idle! Three letters: A-M-D ;) 22 C ambient is freezing. My bedroom is at 23 C and it's colder than where I keep my computer. Maybe it could be as high as... 27 C here, I don't know. Nah, it'd be between 18-20 should by GF not complain ...

Room temp is around 25 C. I have no thermometer so I'm guessing. CPU at idle is 46 C, stressed 55 C. Case temp is 36 C at idle, 40 stressed. Graphics card has no sensor. Shouldn't the CPU's temp be lower?? Especially the idle temp! To compare, olyar15 had an idle temp of 36 C with a much more power...

It's interesting at least. Definitely it will draw some juice from the wall socket, but how much exactly is to be seen. What I'm wondering is that the heatsink must get pretty hot, so you should take some care when installing it for not to overheat any other components, on the MB nearby or somewhere...

The NV78 from DD is a much better block in all respects and at almost the same price. In many respects, but not all. To summarize it: Pros: Even if your card is not 1:1 the reference design, the miniblocks sit firmly on the memories; the monolithic block might leave sub-millimeter gaps somewhere wo...

Editor's Note: The reality is that the noise reduction with the Nexus 120 fan as you go below ~8V is pretty much inaudible in just about any system, so there's really no reason to run it that slow anyway. Of course, if you have a noisier fan... I think the original writer meant that you do not need...

that thing looks like it was design to hinder flow as much as it is possible in that given space :) Well, do your math: if you use 10/8mm tubing for rest of the system, you have cross section of about 50mm2. With 8/6 tubing it's about 28mm2. Four 5/3mm tubes parallel mean 4*6mm2 = 24mm2 cross secti...

I would like to cool the CPU, GPU, and the NB in this loop. My only real concern is that I have heard of people having problems mounting Zalmans waterblock on the chipset, as the GFX card(s) overhang it slightly, and are in very close proximity. I plan to use old Zalman GPU block on NB on my A8N SL...

Water-cooling.com sells the acrylic top separately, if you want to try it out: http://www.watercoolingshop.com/catalog/product_info.php?cPath=42&products_id=408 I am trying hard to find the original cover to repeat the tests with it, but no luck this fa...

I have soldered a trimmer pot to the PAPST to be able to fine-tune the voltage level, but as I wanted to use only known voltage levels I set it to zero resistance. Next step was to do the 7V trick and at this level PAPST fell clearly below the pump in noise level. I had to strain my hearing to hear...
