Now I know ASUS has the best fan software, but it's always been clunky for me. Does FanXpert 2 work flawlessly?
I dont have any issues with FanXpert2, really great software on it own, but the problem is the way that AI SUITE III measure temps, and this is binded into how fanXpert2 will control the fans. Asus has its own way of measuring temps, accoding to Asus JJ, its not core temperature, not pack, but a formula using mulitple sensor that they say its more accurate representation of it, weather its true or not idk, but fact remains that it will not match to any software out there, and its not linear either, sometimes is lower and sometimes is higher than other software. There are mulitple threads about it, ill leave you one of the last that i posted, Hero Temperature Sensor difference and Fan Xpert 2
And what motherboard would be best? I'm leaning towards the Gigabyte Z87X-UD3H.
I dont think a best one exists, all have issues, some matter to some others dont care, etc. If you like Gigabyte go for it, i dont have much experience with their latest offering, so i cant say. If you are looking for good bios fan control look into MSI and AsRock, if you want software based i would say asus is still the best as long as you can live with what i mentioned above. Gigabyte also has improved their bios and software but idk how good is it, either way you can make it work out with fan controllers if all fails.
I'm looking to upgrade to Haswell and I'm having trouble deciding between CPUs for a quiet pc build. The K has a TDP of 84W vs 65 for the S.
My current Phenom II 955 has a TDP of 125W. I can't do this right now with my 955 because it gets too hot. Would I be able to do this with Haswell? Now, I will want to overclock a bit, but the 4670S is about 40$ less and lower TDP.
Personally i dont recommend S or T CPUs as you are getting a factory crippled CPU, even if its lower in price its just a handicap cpu. I would just go with the i5 4670 (K or not up to you), now be warned that Haswell CPU run hot on load, my 4770K reaches above 70C on prime95 on stock clocks, so depending the temps you are aiming, you will need some decent cooling to overclock and still maintain decent noise.
What I aim to do is using my motherboard fan control software, to turn off the fans below a certain point (idle or light usage) and keep them off until load.
I think with Asus you can do that, i never tried it though, but i read some other forum members have, but i cant say for sure as i never really tried, i just lowered mine to where they were inaudible so it didn't matter if they were on or off.
