Re: Passive cooling meets mineral oil: Dual CPUs and Titan X

At least you won't have to heat that room in winter, hehe. Fingers crossed that you don't have to change any components, because that would be messy. How many times did you re-seat the coolers? I would have been paranoid about getting it as optimal as possible. Due to the RMA of the MoBo I had to r...

Re: Passive cooling meets mineral oil: Dual CPUs and Titan X

Well at least the fans will be well lubricated. Can you perhaps provide some more details on the exact oil being used? It would be interesting to be able to look at it's thermal and electric properties. I am assuming the large heatsinks act as radiators from the mineral oil. What kind of temperatur...

Whaaat?
As they move oil and not air I prefer to call them propellers and not fans :)
Also they turn slower than usual, but they are completly fine and I do not need a lot of oil movement.

Re: Passive cooling meets mineral oil: Dual CPUs and Titan X

Congrats, as usual, impressive job, as usual! :wink: Out of curiosity: I didn't understand, did you eventually fixed the mobo whine? How? Is the mineral oil toxic? In case, what about the leaking? How to clean all the parts if you need to do some manteinance work? Thank you very much :) 1: I return...

Passive cooling meets mineral oil: Dual CPUs and Titan X

Hallo silence aficionados! My third passive build is even more powerfull than the previous once. This time with mieral oil. While it uese 3 fans, they are fully submerged and totally inaudible while the oil itself is passive cooled. DSC02424.JPG DSC02426.JPG The specs are: CPU: 2x E5-2680 (8 cores, ...

Re: 500 watt full featured gaming PC - passive cooled [Updat

Hey man, great build! I'm working on 0db PC myself and studied thermodynamics and heat sink optimization a lot, hope to post build log or gallery in here too. I have a straight out suggestion for you: find a way and remove every single rib in your profile - that would increase efficiency of the who...

Cool concept.
There is a big enougth gab between the PC and the wall so I can (or at least could) clean the corner.
Also the total weigth is ~50kg.

But thanks for the kudo ;)

Re: 500 watt full featured gaming PC - passive cooled [Updat

The software from Enermax allows to read out the temperature of the PSU. But the sensor placement is a bad joke. It was showing 60°C while the PSU was actually running at 95°C. Full 35°C difference!?! Which FLIR camera is, and how did you calibrate it? It was an Optris Pi 450. I didn't calibrate it...

Well, a full screenshot with background etc (Furmark image) will be best as an JPEG, but something like the HWMonitor screen, with few colors, will be best as PNG. You could put the relevant windows side to side, take a screenshot, crop the image to remove all the background, optimize the number of...

PNG is the image format of choice for screenshots like that btw. Small file size and perfect quality.

Thx ;)

Well the 2560x1600 screen shot in PNG is 4 MByte. Downscaled to <256kBytes it's only 506x286.

What's the role of the FX-70? I underestimated the transport capacity loss when installing heatpipes upside down. The three 8mm are not enougth to transfer the 100 watts to the big heatsink, despite they are capable of >200 watts when installed with the heat source down. The FX-70 helps me to get r...

Coil whine, a silent enthusiasts worse enemy! Superb build! Thx ;) Yes coil whine is terrible, it really is. By thw way a new build is under construction where I push the limit of a passive system with dual GTX 980. I allready ordered 38 kg of heat sinks! Have a look here: http://linustechtips.com/...

Re: Full passe / fanless >250W workstation: It's possible!!!

why do you have sound absorbing material if there are no moving parts? Only because it have no moving parts by desing, it doesn't have to be the reality. The coils on the MoBo are virbrating a liite bit and I can't reach them to mold them properly. But with the aborbing material I can't hear it any...
