5 C above ambient is a very high performance system. You will likekelly be looking into $70 + pumps and push/pull 77 Bonneville heater core. Even 10C over ambient is a lot of effort in water cooling, it's about $50/1C when you get below that.
Good Luck.
My god, did you not read the thread?
Its IMPOSSIBLE to be 5 degrees above ambient with water. PERIOD. KAPEESH?!
If you're using a maze4, the pressure drop is so low that it shouldnt be that important how powerful your pump is. Just look for something around the eheim 1048 specs, and you'll be fine. Going higher (ie, eheim 1250 range or higher) and you will probably see at most, a 2 degree change... and thats being opimistic.
However, if the L35 is cheap, and its more reliable, go for that, for sure. Head is what counts in pumps, not flow rate, by the way.
Expect to be around the 40 degree mark (real temps, not onboard motherboard temps; they mean nothing. NOTHING)
the best temp you are going to be above your water with a maze 4 is probably about 12 degrees C, give or take. Then, take the fact you've heated up that water, a further couple of degrees (minimum). Add that couple of degrees on, and you've got 14-15 deg C. Then, add that to ambient. This is where you're going to be, with full load. Sitting pretty at 37 degrees in a 21 deg room.
This has all been said by Greenman100, but perhaps with twice the people power promoting it, you'll listen.
EDIT - yes, thats almost exactly what you should see, depending on the CPU and heat load.
