Skinnee Labs - GTX480 Block Round-Up (working thread)

[skinnee]

can you move the sensors a mm nearer the vregs? hehehe

They are as close as they can get and still maintain clearance of the chokes. Sensors are reading 30C+ at idle as I get the system changed over the R2E.

I agree on some points Nickle, but this isn't a watercooling 101 class. Be nice to have one. Skinnee does the deep work and I'd rather him focus on the test than why he uses GOO GONE to pre wipe a CPU for TIM application. We all know that, or ones watching the vid really should know before they get to this level.

Well I disagree. The video is/should be a WC 101 since the people who don't need to hear all the details don't even need the video anyway. The point of it is to teach people who have never done this... And yes, Skinnee's time is best spent testing, so making videos you can only understand if you know how to install blocks is a way bigger waste than making 101 videos. As nice as bling videos are, Skinnee making entertainment videos for enthusiasts is really a waste of his testing time.

Would it not be better to use calibrated thermocouple sensors here? With the Dallas sensors you can't get close enough to the mosfets, which is what you want to be actually be measuring. Sacrifice some accuracy in order to get closer to the action^^

That was my initial idea... use the UEI DT302 I have for LN2, but that was going to be more hassle for very little gain. From the runs last night on the BP block, the sensors are working very, very well. Keep in mind, if NV would've just done the proper design and provided VRM sensors we wouldn't be having this discussion in the first place.

This is a debate I had in dreams between a nameless Hard core XS member and Skinnee:

XS (Authoritative): Ideally Skinnee, you'd want to epoxy 28 type T thermo-couples to the side of each one of the mosfets

Skinnee (mildly amused): $%^%^&you or what? grmbl grmbl

XS (accomodating): ok, I understand, .. how about 14 then ? You could run spreadsheets with temp variations between each of the mosfet with the different blocks, with nice standard deviation curvs.. that would look great!

Skinnee (loosing patience): *(& (^&*

XS (giving up): fine, let's settle for 7 then ? really that's the least you could do for a mildly accurate performance analysis.

Skinnee: (%^&% ^%&*(&

[-Fluffy-]

These results can't come soon enough!

Does the EK backplate do anything functional, besides looking awesome?

I might be wrong but I don't think so - at least not until you put the thermal pads in a few places where there are chips on the PCB.
Perhaps also prevents the card to bend but to be honest I did not notice PCB to bend with EK block.
