Yes, £30(including shipping) is not to bad considering you got 5 fans there as well.
I had one fan in my case and and bought one silent Xsilence Red Wing fan which was about £4. I have only 2 fans in my case at the moment, but heat is not a problem- I have overclocked both CPU and GPU (manually, auto OC is hotter) and both run under 70C on full load.
I've read that Antec fans tend to be louder than most, but yours must have their hydro bearing worn out. A lot of fans use those bearings nowadays because of they are relatively quiet, but the downside is they wear out quicker. Also LED fans tend to be noisier than non LED for all makes it seems.
I am also running one fan on bottom front and one on upper back of the case and it seems to be enough.
I've also cut out fine mesh pieces to cover all the vents in the case and this seems to eb working very nicely- no dust at all in my case after 2 months
Guess I'd better tear down the case and put the cooler on.
You're the scientist, so you cant kill Sarif and put humankind back into dark ages for fear of technology. (Yes you can, its just a game)
Did you manage to win the argument with the Humanity Front leader at press conference? I couldn't However, I found out that I've missed "Acquaintances Forgotten" side mission, so I have restarted the game from scratch (plot branches in the first mission so that wrong choice makes it inaccessible much later on), so I'll have another go at this press conference too
And overclock- otherwise what is the point of a new cooler?
Oh, so that's what it is! I also have about 4degrees difference between the cooolest and hottest cores, I thought it was just down to architecture... My max temps are about 70C (OCed, stock were about 60C if I remember right). I run stress tests for 15 minutes though, and temps do pick up after 10+ mins on my cooler (Arctic Freezer something, wish I spent and extra fiver and got yours )
