prime small ftt

Whenever I do prime small ftt my temps shoot extremely high 90+ but when I use blended mode they stay normal max of 50-60 is there any reason for this i7-4790k

Small is the most power intensive calculations, Blend runs a mix of Large, followed by Small so initially you'll see much lower temps in Blend.

but 40C extra? it just seems odd

Blend uses the RAM a lot so the CPU will spend a lot of time (in CPU terms) waiting for data compared to small, which is stored in the CPU cache so the CPU is kept far busier.

Like Jokester says though, if you run Blend for long enough it will eventually run some small and your temps will go up much the same.
