ASUS HD5450 heat dissapation

post #1 of 3
Thread Starter 
So, I thought it wise to get the above mentioned GPU for my HTPC, it performs great and certainly does all what i've expected and needed it to, especially intrigued by the silent no-fan built, I just thought it perfect...

Having a small case (Silverstone Milo) it gets a tad cramped and I expected a bit of more heat over the norm due to the bad airflow, there really isn't much room to route your wiring in... With that being said, my GPU sits at 72°C Idle, spiking 81°C on full load, which is scary to say the least.. I've already tried re-applying the thermal paste, which only really gets me a 2-3°C improvement, at this point I'm not sure if I even want to keep the HTPC running, I can't seem to get better airflow to it or even lower its idle temperatures in any way.

Would you recommend ditching it entirely, grabbing a better heatsink for it or perhaps someone already made experiences with the HD5450 similar to mine, I don't mind a bit of heat seeing how the 3 HDDs and even the CPU rock a solid 25-30°C in idle (Though, it is summer right now and the room temperature's spiking up to 24°C), but I feel 70°C and rising is just a wee bit excessive at this point.

Little updated, a fresh cold boot leaves the GPU's idle temp at around 32°C for a few minutes, while doing nothing but starring at the desktop with minimal services running, windows classic theme and nothing but speedfan, it barely takes 10minues for it to jump straight back up into the 60's.

The 5450 is safe up to 85C or so. Nothing to worry about, but it clearly doesn't have the best cooler on it.
