I'm about to try watercooling for the first time and wanted some advice on applying TIM. I use the single blob method with CPU's and it works well for me on Sandy Bridge CPU's (single smallish blob on middle then let pressure spread it out).
I was wondering if it is the same with gpu's? Are GPU's larger than CPU's (have not got stock air cooler off yet)? I saw a video where the chap used a central blob of TIM then four more towards the corners of the GPU. This seemed a lot of TIM to me but perhaps GPU's need more. I'm aiming to get this right first time as refitting a waterblock to change the amount of TIM later looks very time consuming.
Any thoughts would be appreciated.
