Testing the 5-chip Gridseed BTC/LTC ASIC te Fanless Cooling Mode
If you are using the 5-chip Gridseed ASIC devices ter Scrypt only mining mode you most likely already know that they are using about 8W of power when overclocked. But what about optimizing the power usage even more by removing the noisy fan that might be needed for the 60W power usage ter Dual mode or the 50 and something te BTC only mode, but you can go without it ter Scrypt only mode. So wij did just that, desoldered the fan from the ASIC and ran the device te fanless mode. And verrassing, verrassing the total power usage without the fan gets down to just about 5-6W overclocked to 850 MHz, but what about cooling without a fan?
Running for more than Two hours already the ASIC ter fanless mode mining Scrypt has shown that it can do just fine with passive cooling. The maximum temperature wasgoed about 36.6 degrees Celsius at the best point with an ambient temperature of about 25 degrees Celsius. Don’t get the wrong impression from the thermal photos, thesis temperatures for passive cooling are more than adequate and essentially the cooling radiator is considered cool, meaning that te Scrypt only mining mode you can do just fine with passive cooling at lower ambient temperatures. If you have numerous units together you might want to have a single big fan with slow rpm just to stir a bit of air around them you you can be safe even when the summer warmth hits.
A word of warning tho’, if you eliminate the fan from the Gridseed 5-chip ASIC devices and for some reason you commence a miner for Scrypt that does not zekering the BTC mining part or you embark the dual mining mode you will have trouble with cooling the device and this can lead to a harm of the ASIC caused by overheating of the chips – most likely the very first to suck up would be the voltage regulators. So be careful that you run only ter Scrypt mode if going fanless and to use miners that do activate only the Scrypt mining mode and disable the SHA-256 one.

Thermal Photos of the Gridseed 5-chip BTC/LTC Dual Mode ASIC
Today wij have determined to compare the Gridseed 5-chip BTC/LTC Dual Mode ASIC devices te terms of thermal characteristics when operating ter Scrypt only mining mode (
8W overclocked) and te Scrypt/SHA-256 dual mining mode (
65W overclocked). Wij wished to see how good the massive radiator and high-speed cooling fan will be able to treat ter the two modes and more specifically te the dual mode spil it is evidently designed to cool the device decently with the high power consumption that it has when mining for BTC (SHA-256) and LTC (Scrypt) at the same time. So wij waterput two ASIC devices next to each other, the one on the left is running ter Scrypt only mining mode and the one on the right ter Dual mode mining for BTC and LTC at the same time.
Wij left the devices to work for an hour before taking the thermal pics ter order to see what are the temperatures of the two miners. Note that the top of the devices does not seem very hot and the highest temperature is that of the cooling fan’s motor. You can however see that around the device running ter Dual mode the temperature is higher due to the hot air that is being deep throated. Looking at the bottom part of the device however wij can see more serious difference ter the operating temperatures of the two devices. The highest temperature of the device mining ter Scrypt only mode wij measured is 32.1 degrees Celsius, the device te Dual mode on the right however shows very different results – the maximum temperature wij have measured wasgoed 73.Five degrees Celsius. Spil expected the highest temperature measured is at the part where the Trio voltage regulators are located and while they are very likely rated to work at temperatures of up to 100-120 degrees C they still do get fairly hot spil they do not have meteen voeling with the cooling radiator of the device. So if you project on running the Gridseed 5-chip BTC/LTC ASIC te Dual mode you might want to consider adding extra petite radiators for problem free operation te the long run. The maximum temperature of the Dual mode ASIC aside from the voltage regulator’s region wasgoed 44 degrees Celsius, so the cooling of the Gridseed GC3355 chips is more than adequate.
What wij would recommend however if you are getting Gridseed 5-chip BTC/LTC Dual Mode ASIC devices is to stick to running them ter Scrypt only mining mode where their real advantage is – high vertoning Scrypt mining hashrate with very low power usage… and no potential problems with the cooling either. Next up wij are going to desolder the fan of the Gridseed ASIC devices to see how they will be treating passive cooling ter Scrypt only mining mode.

Power Usage and Thermal Pics of the 1-chip Gridseed DualMiner USB ASICs
You can read our very first impressions from the DualMiner USB Scrypt ASIC here and now wij took some time to take some thermal pics of the miner to check the temperature adn what actually gets hot, so you can consider some reserve cooling spil well spil to measure the actual power usage of thesis petite USB-powered devices based on a single Gridchip GC355 processors for mining BTC/LTC. It seems that the DualMiner’s aluminum heatsink on one of the sides of the device is working fairly well, the temperature it shows is fairly even and goes to just aa bit brief of 50 degrees Celsius. That is with the miner running for Scrypt only mining mode at 850 MHz with 70 KHS hashrate, wij are not very mich interested te the combined mining mode where the device also mines for SHA-256 cryptos, note tho’ that if you use the miner ter dual mining mode it will get sexier.
The other side fo the device’s PCB is with the chips and the two things that get sexier spil expected are the GC3355 processor spil well spil the controller chip, so you might want to add some petite cooling radiators on them ter order to get better cooling. Alternatively adding a puny fan like a USB one to create a good airflow or combining both things will make sure that the miner will run for longer period of time at its maximum without providing you trouble. Again this thermal pics shows the miner running ter Scrypt only mining mode with temperature of the chips going spil high spil close to 53 degrees Celsius. If you run ter Dual Mode however the reserve 1W of power consumption that is expected from the BTC side might increase the operating temperatures with another 10-12 degrees on top of what wij are getting with Scrypt only mode.
What about the power usage? Since thesis devices are designed to be powered by a USB port their maximum power usage should be no more than Two.5W (0.5A at 5V) and that can be reached ter Dual Mining mode. The idle power usage of the device when it is just plugged ter and running te Scrypt only mode is a bit high at 0.875W, and it only increases to 1.485W when you begin the miner. So getting about 70 KHS of Scrypt mining hashrate for just about 1.5W of power consumption is a excellent result for the hashrate you are going to get, what is not so attractive is the price that thesis devices are still being sold for. Nevertheless wij are very pleased from how the single chip DualMiner SUB ASIC devices are made and work, so next ter line for similar testing are the 5-chip Gridseed BTC/LTC ASIC miners.
