hi all,
i was just wondering how much case fans actually do?

because my cpu temp is about 70 under a full load, with fans on high

and still only 75 under a full load with my fans on low

i have an antec 900 but i only tested for a few minutes on each fan setting

would i be able to leave them on low? or would it be bad?

There are other parts that need to be cooled other then the CPU. I've lost a few hard drives do to improper cooling. Also with tower coolers there is less air flow over the motherboard, so capacitors, the north and south bridge get hotter.

With the antec 900 I would just keep the fans on the lowest settings. anything other then that is just wasted.

Put your CPU model as diferent CPUs have diferent thermal ceilings and maybe for one would be ok 75º and for others you are running at the limit of the Cpu.

For me 75º if very high to run everyday.

Also related to the case fans think that also affect the GPU, you would get an increase in GPU temperature with fans at low.

i just did 2 tests max fan speed cpu was 77 and lowest was 78 i let each run for 5min

so i guess my question now is, like PsyKhiqZero said would it be ok to run antec 900 case fans at lowest even when playing games?
my specs are:
Nvidia GTX 250
intel Q6600 quad core @2.4ghz
2x 2gb DDR 2
gigabyte EP35-DS3L

also if any1 could tell me, is 77 degrees celsius high for a full loaded Q66000 with a stock cooler?

ps: i dont have the optional fan on the side of my antec case

Yes, It's very hight as the Q66000 have a Tcase (if you didnt known about CPU temps, think that Tcase is something like the max temp that the chip could get) depending on the model of B3=62.2°C or G0=71°C, anyway you are running it a lot higher than recomended maximun temperature, the problem for sure is that you are using a stock cooler, have you overcloked the Cpu?

hasnt been overclocked :/ just stock intel Q6600 quad core @2.4ghz how can i tell if it is B3 or G0
and also does that mean i should run my fans at max ? even tho its a 1 degree difference lol?

Im almopst sure that CPUz could give you the concrete model.



That's a diferent think, your problem isn't the case airflow (and that's why when you put more airflow into the case the temperatures remain almost the same) but the CPU.

For 1º I will left the fans at low but for 70º-75º diference i will left the coolers on high (after all you are over the Tcase of your CPU), but if you want to lower the temp i think that your only real alternative is to purchase and install an aftermarket CPU cooler (in your case try with one vertical model that exaust air to the back fan of the case) with a proper themal compound.
