Hello, I'm new here, looking for some advise as I've not really dipped into high power computing before (and doubtless some of you wont see what i'm doing as that high power
). Sorry if I waffle on a bit 
I fairly recently built up a new machine in preparation for the CAD and CFD simulation work I'll need to do for my final year project as University. It's an OCUK 4ghz I7 bundle with the Corsair HS50-1 Cooler built into a CM 690 II case. It has been running nicely since I got it, and my temperatures during normal use sit around 50C on desktop type application and 60C on particularly demanding games.
I've just reached a point in my project work where I've started running some test simulations and when I do so it runs the cpu at 100% on all 8 threads as well as maxes the RAM.
Initially I had it cooled by having a 120mm inlet fan on the HS50-1 on the back of the case and the two 140mm fans. Temperatures within about 20 seconds would hit 75C+ on the CPU (I bottled it and cancelled the run at 80C after a couple of minutes).
I assumed I just needed more fans so yesterday fitted 4 more, on a fanbus so I can crank them all before starting my solver run. This hasn't fixed my problem tho, it just takes longer to hit high temps but it still saw 80C on a 15minute sim.
Once I get going with the proper solver runs for my project they'll be maxing the cpu/ram for hours at a time so this really is a problem!
Heres a quick diagram of how it's set up currently
So my currently thinking about solutions falls into a couple of catagories.
The airflow through my case is wrong, I need to alter the direction of some of the fans, and suggestions would be appreciated.
or
The HS50-1 doesn't have the thermal capacity to transport the large amount of heat I'm generating (the core does seem awfully thin). I started looking at full on watercooling solutions (seperate 240mm radiators, pumps, waterblocks, tubing, etc, lots of parts to these systems) I priced up a set at around £250. I'd rather not spend it but if it's the way I fix this I'll have to.
Does anybody know the largest sized radiator I can fit at the top of the CM 690 II case (I presume top mounting makes more sense as the hot air can be immediately ejected)
