I just read here that the fan speed is based on the ambient temperature of the air in your casing. This was tested by blowing hot air onto the fan, and the fan's RPM bumped up considerably.

A bit of my results for CPUMSR...

Enabling Fast Strings and disabled options on CPUMSR did not improve any performance on Sisoft Sandra, but the program claims to increase performance on applications that utilise it.

If I'm not mistaken it's the P4 Extreme Edition at 3.6GHz, if your motherboard supports it.

Just buy a new battery then.

Very obvious that your PSU's the culprit. If it's possible, get a high quality one. I have an Enermax 350W which is powering my PC very nicely, which has four 80mm casing fans, two hard drives and the rest listed in my signature.

Haha, close to 3.8GHz is already a very good achievement. Let's see how much more pressure it can take

kabukiawie, how much are you planning to sell your 7300GT?

My peak temperature is at 65C, if there's no air-conditioning running

In my opinion, getting a new cooler for the 478 isn't future-proof, so I'd rather not waste money on that

There are a few recent aftermarket heatsinks that do support the 478s, along with the newer sockets. But, what I meant in a sense that the newer heatsinks aren't compatible with the 478, and you have to get an old cooler which might not be efficient enough to cool the latest processors.

Actually, I thought of getting a second-hand aftermarket cooler myself, but after seeing how you can't go far with a 478, I just felt is wasn't worth it. No matter how much you push the processor with the best cooler you have, the performance isn't gonna be on par with the C2Ds or X2s.

Might as well, save up that money to invest on my next PC.

Just made a small check. My processor runs at 70C when running SP2004 at 3.6GHz on stock voltage

BurgerRI, what are your temps on 3.88GHz, full load? And what HSF are you using as well?

@sang_karim

Any reduction in temps after opening the 5 1/2" bays? And also, just noticed that you're gonna be a father this month Congrats

Today, I tried removing my side processor air duct. The processor fan started running up to 3300 RPM from the usual 2700 RPM, however temperatures were still 70C.

Shows how an air duct could really help in the cooling process.

@kabukiawie

I know 70C is on the high side, but I usually do tests on worse case basis. I usually run my PC in a cold environment, so the temps usually drop down to about 62C.

I just did a bit of rewiring today to clear the airflow, now stress testing the processor without the duct and cold air to see the maximum temperature achieved

One of my RAM cooler fans just failed on me, will get a new one soon to replace them. No wonder my RAMs are hot to the touch; that must be the reason too why I fail SP2004's Large FFT tests when the air conditioning isn't on.

A 60mm fan? A 5 1/2" bay is 40mm tall, which is shown in sang_karim's picture, his 120mm fan took three bays to fit in.

How did you get one and a half bays free?

As for the RAM cooler, the fans are slowly dying down... Luckily the cheapo fans can be replaced, so I'm planning to get better quality ones.

LOL oops didn't notice that

But a 5 1/2" bay is 40mm high, I slotted three 40mm fans into the opening in my old PC to cool things further.

In my book, random crashes and hangups ARE major problems.

I guess what shinjite meant was a component in your PC, which I suspect to be the motherboard might have failed, eg. leaking capacitors, failing MOSFETs, and such.

My old computer also has this problem, but it can be solved temporarily by switching off the PC for a little while, then switch it back on again.

@pengster
What graphic card are you currently using with your P4?

@kabukiawie
Sleep in the dustbin? I smell a new motherboard coming up

Underclocking might save a lot of power and might make your processor last longer, but I always prefer to run my PC at max speed.

fylon, how's your PC doing in the Large FFT test in SP2004? Is it stable with your current stable setup?

Mine gives me errors when the heat builds up, but if done in an cold room, it goes error free.

Lucky for you, you have a Hyper6+ installed. My processor on full load used to reach 70C-72C, but now after cleaning the heatsink plus a bit of lapping it has gone down to 65C.

Wow, 270FSB, real sweet. My D43s could only run at 260FSB with 3.3v pumped in.

About heatspreaders, I don't know if it actually works or anything, but I used to put individual heatsinks on each of the RAM chips and put a RAM cooler over it. It did cool down things though

Guys, any cheap S478 coolers to recommend? I feel I shouldn't let my 3.0E take the heat all the time

It's best not to get any video card with 64-bit memory datapaths, no matter how fast the memory or core runs, it's all limited by it.

My Radeon 9700 PRO still serves me nicely, although old but with the 256-bit memory datapath, it is still able to play the latest game albeit with mid-range settings.

That's kind of true, but still most upcoming games nowadays rarely utilise SM3.0, and usually have SM2.0 as a minimum requirement.

And if you wanna change your graphic card, you have to change your rig. Man, stuck between a rock and a hard place...
