ASUS GTX780Ti DC2OC _ VRM are Very Very HoT!

[Fastx]

Sensors Mis-Placment?

Not sure on your pic but I am going by that Guru is measuring the correct VRM area for those temps with their TC. The ASUS rep says its a wrong sensor reading but Guru shows with their TC the temp to be around 100c. I don't know the Asus card well or VRM placement on the board but right now I am leaning to Gurus' finding at this point imo

The previous Asus reply came from here after googling which refers to the R9 290 which isn't the same card as the 780ti.

The Asus rep explained that the sensor is not placed correct next to the vrm and max ir temp in guru3d could be picking up the max temperature of some other component (don't know if that sounds plausible). That could be easily verified by eyeballing if the sensor is visible on the pcb. The rep didn't explain why the core gpu temps are lowered by an offset though.

I don't know sounds like a little tricky talk going on imo but I could be wrong. I am going on Guru TC pics so even if the sensor is misplaced they are still getting a high reading. I first read on that forum that the sensor was reading the temps incorrectly not that it was misplaced I believe.

I made the mistake of posting the wrong link which should be this one:
http://rog.asus.com/forum/showthread.php?46389-ASUS-GTX780Ti-DC2OC-_-VRM-are-Very-Very-HoT!/page2
The OP also made the above thread on the Asus forum.

you have to wonder why some peeps go to water after post/threads x [? 110k] about gpu high temps in every forum.
-until big max. comes out with 14 billion trannies under 150 watts ,water is still cool imo

I just rade the Asus tech' replay on the heat of their Crads, here it is:

Lucky us that ASUS decided to use 105°C rated caps when the VRM runs at 104°C! :whiste:

Add more airflow over that area if it's not too difficult to do in your case. VRM's run hot on the newer cards, but it's been generally due to lousy engineering of the cooling setup. So it's often a pretty straightforward adjustment to get better temps. Either upgrade/add the heatsink to vrm's or add some more air movement over it.

What do people think about the possibility of solder melting at these high temps?

 

[magomago]

if VRM runs within spec, and the card performs within spec, what is the problem?

What do people think about the possibility of solder melting at these high temps?

Alloys commonly used for electrical soldering are 60/40 Tin/lead (Sn/Pb) which melts at 370 °F or 188 °C and 63/37 Sn/Pb used principally in electrical/electronic work. The 63/37 is a eutectic alloy, which: has the lowest melting point (183 °C or 361.4 °F) of all the tin/lead alloys

No.

Old thread guys.

 

[Attic]

haha yea, I missed that. But glad 3DV posted, Deders had me thinking.

 

[alcoholbob]

Are they hot and Taiwanese?
