@srs2236Ahah, it wasn't really like that. The soldering work was carried out by my friend, but under my careful supervision There was no soldering dryer, only a special thin tip for the soldering iron.
-
@MiRaGe @srs2236 Repeated this mod. I added tantalum capacitors on the back side of the board, and was able to achieve a stable 2085 MHz on the core, with a slight addition of voltage. The memory OC capabilities remained unchanged, only +1050 MHz. Card consumption is approximately 270W. (due to previous shunt mode)
-
@MiRaGe what specific models of poscaps did you add? I plan to add EEFCX0E331R, 330uF; 2.5VDC.
-
My typical shunt-mode temperatures are around 50-60 degrees for the GPU. Approximately 250-260W.
-
@srs2236 It's so cool that I want to do the same. My 2080S board also has unused places that are worrying me. I have a shunt mod done, but adding more POSCAPS seems to give me more headroom for OC. wait soon

So far, there is nothing better than a vapor chamber, and I am sure that the performance of a solution like on the picture should be amazing.
-
Yesterday I accidentally found this cool custom heat sink for the good old p775 on taobao . It has two integrated vapor chambers for the CPU and GPU, as well as larger grill areas where the fans are installed. (it seems that the rear decorative panel on the case needs to be removed to install this monster) It looks massive, heavy, and powerful. There is also the option of separate gpu and cpu heatsink, also with vapor chambers. The price is about 150 dollars. Pretty sure it can handle 400W+ heat with custom fans.

Do you have access to taobao...?

I think there is a software problem here, because TimeSpy (especially extreme) is much harder than the same Warzone.
-
Both points play a role here. The 2080S has better quality chips. Even under heavy loads, the frequency does not decrease? Any benchmark results? Is it only in one game?
-
Oh yes, it's quite an adventure to tighten the screws on the heat sink without having any problems with the pressure on the CPU. The vapor chamber of the stock heatsink does an excellent job with the GPU side, I think this is more of a problem with combined loads. I am on 2050Mhz@993mV for core, and +850Mhz for vmem now.
-
To determine this, I will order two wattmeters for both power supplies, this is the only way to determine the real consumption. I think about 250W or so. I once again went through all the thermal pads, and changed them to new ones from Laird. Due to water cooling, the GPU and VRAM do not heat up above 60 degrees. Due to the change of thermal paste to another and the shunt-mod, the previous results are no longer relevant.(

Hi all. Finally found time for something interesting. First, the shunt mod for the video card. A thin wire was soldered around the current-measuring resistors, which is why the consumption in software monitoring became defined as 120-130W. Thus, now there are no problems with a stable core frequency at the level of 2050-2070 MHz, I have not tested it higher yet. Since the laptop was disassembled, at the same time I installed custom fans. They are on average 25-30 grams heavier than the original ones. Their main advantage is that they are MUCH quieter than stock fans. At the same time, the air flow is quite strong not only at the rear, but now also at the sides. However, if you look at the monitoring of the CCC, they operate at a slightly lower speed: At low speeds, they are not audible at all, with an average load, they begin to make a barely audible noise with air currents, but they are not as annoying as the original ones. I didn’t try to check it without water, so I can assume 5-7 degrees of gain + much less noise, as it was on 775TM, about efficiency.

A lot of work here, I'll try to put it in on the weekend
-
It's time to upgrade the air part of the water heatsink)
-
0.95V. I plan to make a shunt mod to bypass the 200W limit and provide stable 2150-2200 MHz.

You must be registered on taobao to view listings. There are no other links.
-
Sure - link. ~50$ for CPU+GPU
-
On aliexpress there is not even 10% of cool custom items that are on taobao. In addition, aliexpress is very inadequate prices.
-
If you need links to custom fans for p775tm - I can help you. The main thing is to find a way to buy from taobao. They are almost twice as quiet and allow you to win 5-7 degrees. I had these on the old p775tm.
-
It seems to me that on the kryonaut extreme temps should be lower. Not much, but still.
-
@MaxxDwhat thermal paste do you use?
