MSI GTX560Ti Memory Temperature

[MultiCofy]

I've been playing StarCraft II for some time now and I noticed that my fan started unusually faster for a seemingly not so GPU hungry game, implying it was under heavy load and temperature was rising (know that since I've got the custom FanSpeed curve set up). So I decided to drop a look at MSI Afterburner measurements while playing StarCraft.

There, I found something utterly confusing to me:
GPU core temp was maxing out at 84°C - I figure it's not that big of a problem since it's under 100% load, but the thing that surprised me was GPU Memory Temperature - flatlined at 105°C and the line was yellow (compared to others that were green).

I realise I may have typed more than necessary, but tl;dr version is this:
GPU core temp maxing at 84°C, GPU memory temp was all the way up to 105°C. Is this normal and/or should I be worried? What should I do if that's a problem? Why is there such a big difference between the two?

Also worth noting, it's been overclocked to following values:
Core Clock - 950MHz
Memory Clock - 2100MHz
Voltage - Auto

emmory get allot hotter than GPU cores. both of your temps look fine to me

i miss my old gtx 560.

this is one of my old runs through 3dmark

Core clock 999 MHz the best ever for me was 1100 till it over heated
Memory bus clock 2,250 MHz
