Just upgraded my PC's hardware again and Im noticing my system temps are running quite a bit higher (40-45C) than normal

Spoiler: Show
Asus Crosshair AM2 Mobo AMD Atholon 64 X2 5600+ BFG GF8800 GTS on a 850W PSU

My case is a NZXT Lexa and already has 3 120mm fans and a 80mm. Space is kinda tight. What options do i have to keep my shiat from smelling like overdone popcorn?

Not alot, your going to have to be more specific. There is no way your hardware should be overheating, unless you are over-clocking, or it is faulty.

Your power supply is extremely over rated, I wouldn't be suprised if that was generating all the heat.

For system temps do you mean with on-board sensors or just the Lexa's readout?

I have the NZXT Lexa as well. The cooling is actually pretty good with this case if you keep the screens clean. The hardest one to clean is the filter for the 120mm fan up front which can only be accessed by tilting the case up and using an air can.

I don't know if the psu could have too much effect on the temp, but the 8800 and 5600+ both probably generate more heat than your old hardware. If you have a new HDD such as a Raptor, it can generate more heat as well. What was your old setup?

If I'm not mistaken, nvidia recommends a 750w psu or above for SLI on the 8800 series cards. (which he may run in the future)

old gear was a 650 PSU with a 2 7600GS' cards. 939 ASUS A8N32 mobo with a AMD 4000. And i AM using the readout temps. havent checked my BIOS temp readouts as of yet.

I'm using a Thermaltake Big Typhoon on my system, which is a bit older already. It keeps the temperature quite low even though I have a small case and only one additional fan running.

If your CPU-temperature is too high I'd replace the thermal-paste. Get something decent like the latest Arctic Silver products and make sure you use the right amount. Also make sure to remove any plastic-pads from your CPU-fan. New thermal paste will need a few days to distribute properly, but then it might help, especially if you used too much during installation.

Another thing you could try is a BIOS-update, one of my Asus-boards showed temperatures which were 20 degrees too high until I did that. I think they have something called live-update, with that tool BIOS-updating is very easy.

Swapping back in the old PSU might bring down the tempurature a few degrees.

What are you even worrying about? 40C-50C is nothing for most computer components.

...Unless you meant 40C-50C more than usual (must have been at least 30C-40C to start with, so we'd be talking 70C-90C with the increase added on) in which case I'm suprised your AMD chip hasn't imploded yet.

Like I said. His hardware is fine, he shouldn't be worrying.

Have you looked at watercooling or 3 phase?

I have used the Vapochill PE to some success, they are beginning to become quite cheap now, so if your a real enthusiast you might consider it.

Otherwise consider some delta fan's , pretty much the most powerful fan's you can get for your home box ;-)

Personally though that would be quite loud and then you'd have to make an excuse to make your own fanbus (or volt limiter) - not always fun if you don't always know exactly what your doing!

good luck duder,

PS: If you've replaced the CPU (or heatsink) you *really* must re-seat it. If space is tight you will need to cut a hole (sorry but there isn't really any other way to deal with space, other than remove it if its not necessary).

PPS: Make sure your using a high quality paste like arctic silver 5 or Ceramique, I love my ceramique (note to self: you should be careful though some of them are conductive electronically too, so always best to check). A good paste (and/or heatsink) properly seated will decrease your temperatures if its really that important to you , hehe.

PPPS: If you have replaced your heatsink/CPU what paste did you use? If you did reseat your heatsink recently its worth having a play. If space hasn't really changed in your case it could very well be the heatsink's sitting. Of course if you've upgraded to a core 2 duo (or similar) Heat rises are very normal. I've noticed they run a good 50C even on well seated stock heatsinks. If its a small case expect upto 60 or 70C - which is perfectly safe on the C2D's they are rated by INTEL at 110C IIRC. still dude, don't be pushing 70C on one, it's really no good for it - and it'll last a few years less of the 1 - 2 decades you'd usually get from a well treated one. Doh, Since I've just noticed your using an X2 You can ignore this bit. But it's probably helpful to you so I will leave it in! ;-) X2's will run happily upto about 60C then your entering "I really shouldn't be getting this hot" territory, anything over 70-80C is plain madness in my opinion though ;-)

PPPPS: If your running at 50C (and not 50C more than normal) you really shouldn't really have to worry about much duder.
