Why are my case temps so high?

[JungleMan]

My case temps are anywhere from 36-40C...I can't figure out what I'm doing wrong!

I've got a Lian Li PC-70, with 2x32cfm Adda exhausts, 2x32cfm Adda intakes (they're set on High), 2x Panaflo M1A exhausts at the top of the case, a dual-fan Antec TruePower PSU, a Thermalright SK-7 with 35cfm fan. I CANT FIGURE IT OUT!!

I tried removing all of my PCI and AGP cards, removing my side door, even taking my hard drive cage out, all to no avail. My house is probably not even 30C. What the heck is going on?? I had similar results on my Antec SX840.

Someone please help, I've been going mad for days trying to figure this out! I am monitoring using Winbond 3 on the 3/03/03 BIOS.

Make sure all your fans are functioning and pointed in the right direction, sorry it's all I can think of at the moment. After re-reading your post...How sure are you of your temperature reporting accuracy?

Yes, the two in the front are aiming in, and the two in the back are aiming out.

I tested in the BIOS and in MBM. Strangely my CPU temp isn't too bad, right now it's at a mere 43C load but that's with the case door open...

It still bugs me why my case temp is so high, one of the reasons I bought this case was to get nice chilly case temps. Yet my case temp is 39C right now and everyone else's is under 30 with cases that have far less fans! And my house isn't evne that hot...

I take it your reading the case temp from the mobo sensor.
Keep in mind this is a surface mounted component and may be near a source of heat on the motherboard, this may be giving you slightly higher readings. Also the temp monitor isnt allways accurate and can be out by a few degrees.

What motherboard do you have?

[JungleMan]

Thanks Soul, does anyone know where exactly on the board this sensor is located?

[Soul99]

what is your motherboard?
i located a few using a can of spray air held upsidedown, it freezes the motherboard.

I have an Epox 8RDA+ 1.1, using the 3/03/2003 BIOS.

Clever devil! any ill side effects?

[Soul99]

I used to have one of those and the case temps did seem a little high, tho at the time I used no case cooling at all and just leave the side off.
have you got a heatsink on your southbridge?
mine didnt come with one and the south bridge was roasting hot.

I'f your brave put your finger on the south bridge now, if it burns thats prolly whats raising your mobo temp and giving you seemingly higher case temps.

[Soul99]

No Daniel, used to do it all the time.
Its also good for using on the heatsink, freeze the sink to -40 and then turn on the pc > go for some mad windows boot speeds.

Thanks Soul99 I'll add it to my list of tricks! ":O}

[Soul99]

just watch out for little droplets of water, they do form but usually not enough to do any flooding or anything like that.

[JungleMan]

Moving back on topic...does anyone know where the case temp sensor is on the 8RDA+?

[Soul99]

is your south bridge hot?
i'm looking for info on the location of the temp sensor, i've seen one review that says its actually the northbridge, but i bet yours is hotter than 40c, assuming you have the normal round cooler and no fan.

[JungleMan]

Yep I'm on stock NB and SB cooling, right now at 176fsb..(it can do more)

Southbridge is warm, but not exactly hot.

If it's right next to the Northbridge, then that's a really stupid place to put it

[Soul99]

hehe, just got the board out of my cupboard >
it died over an hour period when it became unstable and then half the stuff in the bios didint work and then it would no longer boot. looking around for it.

[Soul99]

"the MB temp sensor is down near the Winbond sensor chip bottom left of the MB"

I found this on these forums after doing a search.
may or may not be true.

[Soul99]

well i cant find any info on the web and i cant visually find it on the board. from experiance tho it looks like any of the other small resistor things on the board so i doubt you could spot it anyway.
Maybe if you could get an epox tech to confirm its location? might be worth a post on the epox boards section.

[Soul99]

At 200 fsb my south bridge was burning hot, i remember the burn > chopped a GlobalWin FOP-38 heatsink in half and stuck that on, which is now cooling my current south bridge.

[Daniel ~]

Yeah, that's kinda what I had in mind.":O}
