Do you fans suck or blow?

Mine suck, all 3 of them, on the bottom of my 8790.

Omaha was told one should blow and 2 should suck by Sager. I am not sure at all that that is correct.

What do you all think?

My fans are all over me. Sometimes, when I have an off day they blow but when I am really on top of things they suck. Its nice to have the fans though...you always say...Let me have my privacy...but what the heck, when they are willing to do both sucking and blowing...I dont really care if they respect my privacy or not

Being a celebrity has its advantages for sure

Hmmm...can you really tell if a fan is an intake (notice the use of this word instead of suck) or exhaust (this word instead of blow)? I learned from CPU fans that intake fans can also appear to be exhaust because the air extracted by it deflects off the surface beneath it and travels back. So what appears to you as an exhaust may be instead an intake.

Posts like a few responses to this thread are where the mean (and certainly the modal) age of the forum cohort are most easily observed.

Good luck with your endeavor, ECO. Do wish I could provide a bit of input.

You might be wrong...
Marquis is some 50+ IIRC
I am 23

so the modal is probably your age

Ack!

I'm 50+ and I used the age old method of determining if it was an intake or an exhaust by using "Smoke". Then I asked a Sager Tech (Ty). Ty stated it should be an exhaust fan after asking one of his co-workers. Don't know that was a correct response, but it did "match" what my unit (at that time) displayed. He also stated that the was used to dissipate the heat from the heat shield in the keyboard area as well as the memory cards.

Perhaps I should redefine my original assertion to be "mental age".

Also, I could be 23 or 50+ myself. Do not believe there was any allusion made to my own age.

"Smoke" of the carcinogenic or the home improvement variety?

If it helps the original poster or others at all, most home improvement centers sell a fine powdery substance in a small squeeze bottle that produces "smoke" (of the non-carcinogenic variety) for testing framework/insulated areas for leaks. Of course, one should exercise caution when allowing any substance near one's machine; however, for a short test, this substance should be quite benign.

Tm,

It be the cancer causing variety. Too cheap for the other kind. Could have used a small candle; however, didn't want the candle wax to go into the machine because the machine could react badly to that; however, will not acquire cancer with such a short contact with the smoke.

I placed a very thin ply of tissue paper, slightly larger than the fan itself, by the fan and watched it get pulled right onto the fan and stay there until the machine was turned off.

The two larger fans are obviously on intake, as they have enough suction to keep regular paper stuck to them.

I don't recommend anyone doing this for extended lengths of time, as this will only cause your system to overheat. But for this exercise, it surely proved that, on my 8790 at least, all three fans take air in.

I'm no thermal engineer, but I certainly wouldn't think having a fan on exhaust close to a fan on intake would be a wise design - you'd be circulating your exhaust right back in. Unless we're talking about turbochargers, I'd think havin them all on intake, with the heat exhausted out the back away from the fans would be a better design.

All 3 fans on my unit are intakes. Used tissue paper to test.
