OpenFoam heat transfer convergence

I am simulating a conjugate heat transfer problem, some solids being cooled by a liquid and using the chtMultiRegionSimpleFoam for this. However, the convergence is very very slow, for example the temperature of the fluid at the outlet changes by 0.001 deg cel in 3000 iterations. I have tried to change the relaxation factors and have played with the different solvers but nothing has helped till now.

Thanks in advance for any insight on this.
