XP 1900+ Too hot, I'm stumped

[Drinier]

I have an AMD XP 1900+ on a Gigabyte motherboard in a 330w Antec case.
With a coolermaster Fan and sink I had my processor running at 54 degrees celcius idle and up to 62 degrees under load. Ambient temp in the case was at 30-32 degrees celcius.

I just put in a Volcano 7+ with articsilver 3 thermal compound because I heard that this combination was great. I followed every installation instruction. I was expecting to see the temp drop a lot to around 38 or 42 degrees celcius.

Instead it is running around 52-54 degrees on idle and up to 60-62 degrees under load. And the ambient temp is now running at 38 degrees. None of the fans seem to be fighting for air flow. The RPM's on the 7+ is the medium speed at 4800. Even on the highest setting it only drops a degree or two.

Does anyone have any help or idea as to what is the problem?

If anyone needs the exact model of Motherboard I will get it for them I don't have it in front of me right now.

Do you have any case fans?

The ambient case temp would be my guess. They're up 6 to 8 C above your previous resuls. The new HS is doing pretty good considering it is working with much hotter air.

[Drinier]

3 of them.

There is an intake fan in the front and two exahaust fans in the rear of the case.

The power supply has it's own fan but I doesn't contribute to the air flow in my case.

But why would adding a different fan cause the Ambient to increase? And all of the reviews I read were of comparable systems and they all lowered the cpu temp quite a bit. It seems to me that I now have a better fan and heatsink and it is running the same if not worse since it made the ambient temp go up?

I thought for sure it would at least lower the cpu temp.

Maybe to much arctic silver on the heatsink.

You've got an near Identical set up to mine, except that I have a 1600+.

I started at 54 and after reapplying the HS and paste I dropped to 52. Go bet says it is the case temp. I went down 10 when I took the side off and directed a box fan at the HS. Bind up your wires and buy a dremel. Your going to be doing so carving.

Yeah, get round IDE cables and make a blow hole. :D

Just a sidenote: I happen to know Drinier and I have seen his setup. What stumps me is that my 1900 xp is overclocked along with my vid card, I have a cheap cool master fan and sink, my computer is in a room that is about 85 degrees, I have one less case fan than him, and my cpu runs at 55 under load. very strange.
