alternatively - you can use ccminer-todd1251-x16r-v2.2.5 for ZCoin too - this algo runs GPUs cool, nice.
Thanks for the recommendation. Have tried that but my rig gets 20% more hashrate with ccminer-tpruvot-v2.2.6-cuda8.0, but still inferior to CoolMiner according to the hashrate reported at pool side.
