This talk discusses the adaptation of the analogue hadronic calorimeter (AHCAL), originally developed by the CALICE collaboration for the International Linear Collider (ILC), to meet the demanding requirements of future circular colliders. The AHCAL is based on the SiPM-on-tile technology, where the HCAL Base Units (HBUs) combine scintillator tiles read out by silicon photomultipliers (SiPMs) with embedded front-end electronics. For the linear collider environment, no integrated cooling system was necessary, as power consumption was effectively managed through power pulsing. However, this approach is no longer feasible due to the significantly higher interaction rate in circular colliders, requiring the electronics to remain continuously powered. This must be achieved with a small temperature gradient to ensure uniform SiPM gain and with minimal additional material to preserve the detector's physics performance. To address this challenge, an integrated cooling system is being developed. In this context, a dedicated dummy PCB was designed to allow systematic tests of different cooling strategies. Initial tests with a copper plate thermally coupled to the PCB and the resulting PCB temperatures will be presented.
