> [@mcm-mike](#): > > I will try my best, if you have any tips for me while disassembling it let me know. If anyone is ever willing to sacrifice an iChicken to the silicon gods (n.b. it does not have to be functional at all; it can be partially or completely broken), there is a lot of information that can be gained by getting the chip professionally decapped and photographed. For an example of what can be done at the hobbyist level: - [The PS5’s actual silicon processor is revealed in these first gorgeous photos - The Verge](https://www.theverge.com/circuitbreaker/2021/2/16/22285947/sony-ps5-playstation-5-die-silicon-processor-photos) - [Sony PlayStation 5 SoC die pictured up close - VideoCardz.com](https://videocardz.com/newz/sony-playstation-5-soc-die-pictured-up-close) From looking at these photos, one can extract information about the structure of the ASIC, the technology node it’s produced on, and even reverse-engineer a rough expected cost of the chip. ---

Good evening. Does the fan have a 2 pin output? Cooler speed not adjustable? Thanks in advance for your reply. ---

I’m not sure but it looks 4 pin. Each one of those connectors is a fan. ![PXL_20210401_011140782~2](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/4/445cc5760f6ac42e359aadcba9f90c45445605c4.jpeg) ![PXL_20210401_011136989~2](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/8/805de3812728c0ef0a0c9bc261ea6d6219c12270.jpeg) ---

If you use a 12v 12.5A 150w power supply, the cooler can be increased programmatically to avoid overheating. ---

Great photos! If the black finned heatsink can be rotated 90 degrees, that would probably be a big win — the airflow would be directly down the fin channels instead of cross to them. I honestly wonder if this is a manufacturing defect. Could apply better thermal paste at the same time. ![image](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/1/10108c02da54cdb7c377d42c2285fc4b44238e67.jpeg) ![image](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/f/f6811b7273a5fc9f7a2745f6d1d8fc72ab0ab766.png) Also make sure that two of the fans are blowing in, and the other two are blowing out. This is cooling 101, but I’ve seen worse in real life… Does it run cooler with the case removed? It looks like the board is elevated a bit, so the plane of the board is at the midpoint of the fans? Is there anything on the bottom of the board that is taking up space? What’s under there? ---

Sorry for the late reply. Repositioning the fans dropped the temp from 96.4 ℃ to 56.1 ℃. Yes, runs cooler with case removed. Some screws were stripped so could not expose the bottom sorry. I took a picture hoping it will help 🙂 ![iPollo G1 Mini](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/7/727f9c5cb4a082e804a86262791024c3938456c2.jpeg) ---

Ahhhh, that makes much more sense — the ASICs are certainly under those monster heat sinks, which are oriented correctly. > [@unpourtous](#): > > Repositioning the fans dropped the temp from 96.4 ℃ to 56.1 ℃. Nice! How did you reposition the fans? ---

I just flipped two of them so the air flows like your diagram. The fans originally came all facing out. Thank you for the tip! ---

Hello. I did an experiment today. I connected emulators instead of fans. I am planning to use CRYSTAL PLUS 70T in immersion fluid. Later I will post a photo after the dive. Summer is coming, it will be very hot. ---

Just connected to the G1 Mini using ssh port 22. Was looking around and searching for the cgminer/asicboard frequency settings. In /etc/init.d/cgminer file there are some settings saved like pwm for fan and pool adress. Did someone figure out how to change the frequency of this little chicken? Pretty sure it can be overwritten - just find the right screw. Would like to do a slight increase to 1.4 Graphs per second since the temperature is far in the green area. iPollo build some fork of cgminer, I saw with command cgminer --help there are some custom calls specific for G1 Mini. But also only for fan control. Maybe it is possible to overwrite the gpio configs, some embedded dev here? ---

It took several years, but here’s what you wanted and what I think a lot of miners have wanted a peek at. Here’s the hot slab of SRAM that makes the G1 mini run: ![1000001158](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/d/d88ea147d359f754868eebfaf0384dfb308531eb.jpeg) ![1000001159](https://canada1.discourse-cdn.com/flex036/uploads/grin/original/2X/e/e6860599ad20c63aac1739a2e5ff9b439c970a61.jpeg) iPollo used pretty nice thermal pads, at least on this one. Will be replacing with arctic silver mx-6 since I’m hoping another power board for the miner can be sourced. ---

If that’s the main ASIC, then it’s not just SRAM but also a lot of siphash hashing units and the overall control logic. We still don’t have confirmation of the amount of SRAM and presence of DRAM outside of this chip (presumed 512MB for holding the edge bitmap). ---

Best to use a Mean Well PSU like the LRS-350-12 which will power 2 units. Also a UPS which should be an APC smart-UPS or one from Eaton, keeping in mind that VA =/= W, for example I deploy a 750VA/500W APC SUA750 for every 4 miners I have. ---
