Overclocking CPU raised temps on graphics card... Is that normal?

Hello there,

I just recently overclocked my 3.0ghz cpu (about 24C idle 32C load) to a 3.5ghz (about 30C idle 45C load) and while i knew there would be a tempincrease CPU wise i have notice an increase in temps on my graphics card as well (used to be 54 load now 62 load) . I locked the AGP slot to 66mhz as well. Is this normal? if not can anyone suggest why this is happening?

System specs:
P4 3GHZ 800fsb @ 3.5GHZ *Northwood CPU
Zalman CNPS7000A-AlCu cpu cooler
vcore is 1.6v
1GB pc2700 ddr ram
PNY 6800GT (400/1100) stock fan *dont laugh im getting my nv silencer soon
DFI lanparty pro875 (A version not the B version)
 
The extra heat that your cpu is putting out is increasing the ambient temperature in your case. Your video card is using warmer air to cool it's heatsink, so it's temps go up. You might want to add more cooling fans to your case, or at least optimize the airflow by organizing the cables inside.
 
the funny thing is my ambient temps are the same. I have 4 80mm fans.. 2 in the back... one in the front and one on the side.. all of them blow in except one of the fans in the back which is an blows out of the case.

Where is the ambient temp sensor? Maybe it never gets hit with the warmer air. The CPU heatsink exhausts near the video card, implying that they would have sort of the same "ambient location".
 
case temp sensor is oftenly verry close to your intake fan.... think south bridge.. heat rises... so i go with what previous poster said

you sure it preforms better with a back fan being intake?
 
What kind of power supply do you have? If it's on the edge and being stressed hard, temps can go up. I've seen it happen.

I also agree with Ryuii that your back two fans should both be exhausting air out of the case.
 
i have a 400w silenx powersupply... and after leaving it run a while my idle temps on my cpu is 24C Ambient 27C. Again im not worried about the CPU temps im worried about my graphics card load temps suddenly going up. My graphics card idle temps are fine.. its just the load temps, and i didnt know if this was because i am overclocking my card.

my power supplys quite stressed... gets quite warm too.. but i have enough air flow to compensate my power supply is running at 110% load after i calculated it :p
