Topic: T17 heatsink glue/paste options (Read 179 times)
As suggested go ahead and use the old thermal setting compound. The 17th are old enough and get hot enough that the top copper layer of the ASIC has actually been alloyed away into the solder and no longer exists as a solderable surface ”black chip”. Clean with a mild acid such as DEoxit Gold for good adhesion. If you wanna go further there are heat sink epoxies I cannot speak to with experience. I am finally there is the traditional Heatsink adhesive, thermal silicone. Lots of options other than replacing the ASIC! good luck
i know about the black glue in china but im afraid it will take long time in shipping that it will make it useless when it arrives ( i read that it has to be cooled in fridge ) and shipping to my country will take 7-15 days not including the customs delays
Black glue does work well for sticking heat sinks to chips and requires refrigeration. But this thermoset adhesive is usually used for S9 and L3+, black glue is usually not used for Antminer 17 series hash board. The heat sink of 17 series is usually soldered on the tin plating on the surface of the chip, so long-term high temperature can easily cause oxidation and the heat sink will fall off. This is the most common failure of the 17 series. At present, if there are too many falling heat sinks, the best way to solve this problem is to refit upgrade heat sink.
I use this thermal glue:

Make sure it was the heatsink that fell off the chip, not the chip that fell off the board. Is the chip surface undamaged?
There's a S17/T17 hack and repair thread here with a pretty decent writeup on how to re-solder the heatsinks but it'll require a bit of equipment to do it right. Bitmain used a low-temperature-process solder which is good for cooling and repair work but bad for operating especially in T-series miners which tend to push high power levels and therefore high temperatures, close enough to melting that the solder gets pretty weak.
Most thermal pastes are not designed as adhesives, so if they "stick" two things together in a permanent bond it's probably because something very bad happened. If a product is designed to glue heatsinks on, it'll say so up-front and words like "grease" and "paste" will probably not be in the title.

Be aware that the heatsinks on T17's are soldered on - NOT glued. Using solder gives almost 1/2 the thermal resistance that any glue can provide. In short - using glue will result in the chip running much hotter but at least the heatsink will stay in-place. Using paste is right out as it will not hold the heatsink in position and the 'sink will soon fall off.
I am looking for some as well but i did just find a company that makes different kinds of compounds for different applications. I sent them an inquiry this morning about what they'd recommend.

hello, i have bought my first miner last month. it was t17 42TH and it came with 1 heatsink loose i guess from the shipping. i didnt find anything locally to put it back in place ( tried some thermal cpu pastes that didnt work like corsair mx30 or whatever ). so now my t17 is working with 2 out of 3 hashboards and hashing 27-28TH only.
i know about the black glue in china but im afraid it will take long time in shipping that it will make it useless when it arrives ( i read that it has to be cooled in fridge ) and shipping to my country will take 7-15 days not including the customs delays
is there a thermal paste you tried and worked and STILL available because i tried to find arctic silver alumina adhesive but its not available anymore
i have found Thermal Grizzly Kryonaut Thernal Grease Paste 10ml locally but the price isnt low enough to buy it for the sake of trying ( about 130$ in here ) and im afraid it will be like the corsair mx30 ( i left it for 3 days and when i flip the hashboard it will just drop )
thanks in advance for your help.
