Re: T70 - can noise be reduced by reducing CPU speed?

I don't think it's particularly loud at all, even at full load, but I don't know what you're expecting. It's using a slightly modified T500 fan, so you can try to guess what it sounds like based on that.

Re: Thinkpadders Rejoice (*LARGE PICS*)

If 51NB can economically make custom motherboards, why can't Lenovo? Well Lenovo would also have to provide support and warranty, among other things. So there are a few more things to consider that 51NB has the luxury of ignoring. It should be noted that 51nb does provide a good warranty and respon...

Re: Can W500 motherboard go into T60?

The T70 looks pretty cool except for the loss of docking support which rules out adding a GT 640 card as described by one user. You can extend an M.2 slot from the T70 to attach a GPU with much better performance than the original dock, although it's up to you to construct a clean solution. However...

Re: T70 with Quad Core i7 mobo for T6x is coming!!

I've applied the liquid metal TIM (phobya) and temperatures are much better. There's one core that's spiking above the others during stress tests (but not real-world testing of rendering) that's kind of weird, but even that is still better than before. http://i.imgur.com/YABwSb1.png Results are simi...

Re: T70 with Quad Core i7 mobo for T6x is coming!!

Buying a camera is excessive... I think a regular cooking thermometer measuring at the beginning, middle, and end of a pipe would work alright for this. It's not super necessary though.

Re: T70 with Quad Core i7 mobo for T6x is coming!!

According to dh3001 from 51nb, the ACPI problems are known bugs and should hopefully be fixed in a future BIOS update. So, just need to work around it for now. Could your heatpipes be empty thanks to (invisible) cracks? Maybe, reworking them (like they did to convert this heatsink from the T500 part...

Re: T70 with Quad Core i7 mobo for T6x is coming!!

I looked at the heatsink with a thermal camera trying to determine if my kinked heat pipe was causing a problem. I did not notice a difference, but I did see that all 3 pipes were not getting nearly as hot as they should. I think this strongly implies that the weakest point is the copper block, whic...

Re: T70 with Quad Core i7 mobo for T6x is coming!!

I was originally trying to get away with removing as little frame material as possible, so I wanted to avoid completely removing the struts if I could. On the strut that remains, I can see that it's no longer pressing on the copper plate or the inductors because I can freely slide a piece of paper a...

Re: T70 with Quad Core i7 mobo for T6x is coming!!

Update on the heatsink. I think I have it under control now. I removed some more material from the frame around the inductors and then removed and reseated the heatsink after reassembling everything. PCB flexing was probably contributing to the problem. Temperatures are now within 5c with everything...

Re: T70 with Quad Core i7 mobo for T6x is coming!!

The CPU temperatures were totally miserable initially. 20-30c discrepancy between the highest and lowest core temperatures under load. The heatsink was making extremely uneven contact with all the pressure on the right side of the die. http://i.imgur.com/0XgKo8t.jpg I lapped the contact plate (you c...

Just took a more in-depth look at this. I had a feigning interest (barred only by $$$$, as usual), but lost interest completely upon seeing a) Kaby Lake CPU (no Windows 7 support), and the Ultrabay doesn't have 2nd battery or serial/parallel I/O connector, both of which I use very regularly in my T...

Re: T70 with Quad Core i7 mobo for T6x is coming!!

QXGA screen is working now. In case anyone needs a solution for this later, the EDID needs to be flashed the same as if you are using the display with a regular T60 (same procedure applies). I thought I had read somewhere on 51nb that it wasn't necessary, but I must have misunderstood.
