Usual tasks like watching movies, browsing etc..is 32-34.

ASUS suite III Mobo utility reports 10 deg less than HWinfo rolleyes.gif I can make the temp lower by maxing the fans (via mobo fan tuning)) but the noise will be too much.


Re:
"ingest their own heated exhaust"- I wish I could see a diagram for this.
If I flip the cpu fan to exhaust air, then I will have to do the same to the side fan.No intake fan altogether! doh.gif

I'm considering another cooler like H5 so that I can have the flow of air in one direction only, keep the exhaust in front and re orient H5 so it's blowing air towards the front too.

Anyways, back to the original question--What happens when a psu fan is flipped? and there is a fan blowing into the exhaust/back of psu.
Is it going to be hotter inside the psu and a much cooler case temp? Thanks doyll for your input.
Here is a drawing of what can happen with downflow coolers .. and how upflow can solve the problem

Don't let all the pretty arrows take your attention away from what the airflow is doing! poke.gif
Hard to say if PSU will run hotter or not, but should run at similar temperature.

whoa that was fast doyll. Now I understand how it works.

Thanks! I'm gonna do the experiment and report back hopefully soon.

Thanks a bunch!thumb.gif

About 18 months ago I built a mITX in an Antec ISK110 Small Form Factor case utilising the supplied Intel fan for my Haswell i5. Its so crowded in there that I realised straight away that the hot air would deflect nearly straight up off the mobo and surrounding parts and crammed in cabling and likely be re-ingested by the fan. The solution I came up with was to cut some kydex plastic I had and make a small shroud around the fan frame and then a sheet cut to fit the mesh grill with a circular opening through which the fan and mini shroud protrude. Thus the fan can only pull air in from outside the case and no air can be re-ingested by the fan. The positive pressure forces air to exhaust out the side vent across the 90W PSU.

That's a simple and effective mod Calibos. Ducting.
Thanks for sharing.

I think I'd do something similar and focus the flow from intake side fan to the fan/heatsink.

Nicely done @Calibos:thumb:
How much difference did the duct and grill blocking make?
The fan style you have can't be turned over and what you did works too. I've done similar in the past. Sometimes pull/ exhaust works better, sometimes it doesn't.

@Mang Keon
I would try reversing the fans first. Rather easy to do and will probably give you the improvement you need. wink.gif
post #76 of 1039
@doyll

So I did some changes in the layout-
No front fan.PSU is attached via 80 to 120mm adaptor in the front. I put an 80mm fan exhaust
HDDs relocated to upper left side above the side fan-now 120mm default silverstone sg-05 fan.




I put the covers of the case and tested like 30 minutes apart-

Reverse fans/Pull:



Normal/Push:


I guess there was little change from yesterdays temps.

Reversing the fans made it hotter by 4 deg celsius.

About 5/6ºC IIRC. BTW, I wasn't suggesting this as an alternative but as further anecdotal evidence towards your point about heatsinks/fan combo's of this type of form factor possibly having hot air re-ingestion issues when in push mode.

Well worth the effort. thumb.gif
First one I did it with was an Athlon XP 2300 or something like that. Ended up switching to a 3200 and more RAM. Used it for many years. Was first system I used aftermarket cooler on. biggrin.gif

AIO (Open Loop) & CLC Pump Specifications

Important Notice:
This is a work in progress. If you have any AIO &/or CLC pump &/or radiator specifications for systems not included please let me know.
Also if you find any errors it is extremely import that you let me know.
Thanks!

The cooler I used with my Athlon XP 1600+ was an Alpha PAL 8045, which was designed to suck air from the bottom and expel it away from the motherboard. And it mounted a giant 80mm fan(!), which blew people's minds at the time. Google "Alpha PAL 8045 review" and you'll see reviewers in awe of the monstrous size of the heatsink. Of course it's tiny by today's standards but in 2001 it was beastly.

Had stock, then w/ duct, then CM Aero7+, w/ duct, then Thermalright SP-97 w/ 92mm fan & duct. It was a beast! SP-97 was like 5 or 6c better than Aero7 .. IIRC, and waaayy quieter. SP-97 was first heatpipe cooler I saw .. and used. biggrin.gif
