Hey guys, it's been a while since I've been here but I've been really busy with school and such.

I finally broke down and decided to splurg on a new computer, here's what I got:

-Asus P5B Delux Wifi Ed.
-Pentium Core 2 Duo 2.4 E6600 OCed to 2.8
-Zalman copper CPU fan
-ATI Radeon X1900XTX
-New NEC 19inch with 900:1 Brightness
-1GBx2 DDR2 800 Ram OCed to 2volts.
-120gb hdd (sata)
-Rosewill 550w PS

I have a question. I feel like my cpu is running really hot, especially with the zalman. underload it gets to about 55c, and i'm using arctic silver 5 and this fan. my voltage is set to auto at 1.36v. I don't know why it's running so hot. i'm thinking the fan may be defective. any ideas? thanks.

Have you taken it off any sweet jumps?

umm... these are the stuff I can think of (if it's not the heat sink fan)

- Pea size thermal paste? Too much/less is no good. (Even if the heat sink comes with thermal pad, you NEED the paste!)
- Make sure it's blowing air out of the case near the CPU, don't blow in.
- Basically don't blow air into the case, only blow air out, to create a vacuum effect.
- Location of the system?

Other than those... I really can't think of any. You still have the original Intel cpu heat sink fan? It's OEM, but sometimes that **** is the best.... Try it on and see if it makes any difference I guess..

I'll leave the rest to the experts..

intel = runs hot when oc'd

AMD = best for oc'ing from my experience

ive overclocked my 3700+ from 2.4 to 3.2 w/o my temps changing

*edit* that HSF looks like it might be a little on the heavy side and when its heavy its going to spread the thermal paste unevenly so make sure the thermal paste is in the right spot and it should perform a little better. IMO

this is the reason i went to liquid cooling in my rig

put it in the fridge with a de-humidifier?

try setting the voltage going to the fan higher, low voltage means low power, so its not performing at its full power.

u could do it from the bios.

i got a pentium 4 HT processor 3.00 GHZ, 512 of ram and 150 gb of hd space wiht an nvidia ge force fx 5200 graphix card.

lol and i dont need all of this power

Schweet systems except that Rosewill PSU, it is a cheapie and can-could cause problems for a expensive system. I have seen it happen too many times.

i think thats a bit too hot, these are the factors that come in to play when dealing with CPU/HSF :

1) the heatsink surface may be uneven, if you take a fine grit sandpaper and smooth it down, making sure it's completely, 100% level & flat, it may help the situation. they call this 'lapping' the heatsink. you normally don't have to do this, but if you notice the bottom of the heatsink looks rough, it might be worth your time.

2) you need more thermal paste. make sure it gets evenly spread on the CPU, not some tiny amount in the center. don't put too much on, but don't put too little.

3) remember that heat rises, so, exhaust fan up top, intake fan on the bottom, usually near the front or rear. it creates a decent air flow in the case.

zalman's are decent heatsinks, but i would recommend a thermaltake / thermalright.

edit: just saw the link you posted for your HSF, i wouldn't bother with it. you need a HSF with more metal, as it stands right now, yours is just a glorified GPU cooler. it's a great design, but it doesn't have enough surface area for the heat dissipation.

WHAT?! Zalman CNPS9500's are pretty big. It may not be as big as a Big Typhoon, but it does have surface area.

To the poster, you probably put too much thermal paste on your heatsink. Thermal paste is not meant to conduct massive amounts of heat, it simply fills in the microscopic dips and scratches in your heatsink that air would otherwise occupy. What I would recommend is:

1) Take the heatsink off, wipe off your old thermal paste.

2) Apply a small dab of thermal paste to the center of your heatsink.

3) Get a plastic bag and wrap it around your finger. Spread the paste evenly around the heatsink with your finger. After the paste is spread, wipe all visible thermal paste off of the heatsink with a towel.

4) Place a SMALL dot, the size of a grain of rice, in the middle of your CPU (not heatsink).

5) Position the heatsink over your CPU and tighten it down.

Thermal paste has sort of a break in period where it needs time to settle and spread. If you do not see immediate results, you'll probably get temperature drops later on.
