A Japanese freelance journalist tweeted this below. If it’s true, it’s only 2℃ left.
She has been one of the most trustworthy source to me. You can read it as an unconfirmed information.

ちなみに今、2号機さん、78度です。裏情報ね笑 Source
<Translation>
Now it’s 78℃ in reactor2. can’t disclose the source.

Jiji reported it was 74.9℃. Tepco started injecting 14.6 tones/h by increasing 1 tone/h.

Have they been increasing waterflow since 2/9 to keep the bottom 2 sensors underwater or to keep all sensors cooler, which implies they have been getting warmer. I wonder what is the maximum pumping rate.
They increased by 4 tones/h in total. It’s beyond the capacity of water purifying system.
Here is a TEPCO video of the Water Injection System as of September. You can see the meters for #3 at 7:22 and they go up to 20(can’t make out the units). They also say that pump 2 is also used to feed 1-3.
