1.4 T bird runs 15C hotter than 1.2?

[Catbird]

Help!! I just upgraded my machine a bit and am having trouble with heating, although it is not hot enought yet to cause problems. I hate to do this but I will list what I had and what I changed, I am sorry to take up so much space, but maybe you can spot something from this.

I was running:

1.2 Gig T bird
Abit KT7A raid
(2) 30 gig ATA 100 IBM hard drives in a raid 0 setup
Memorex CD Rom
Plexwriter 12/10/32A
384 meg of Mushkin PC-150 SDRAM
Hercules Gforce 2 ultra
425 W power supply from PC power&Cooling
full tower with 9 120 MM fans, 4 80 mm fans, 120 blow hole
( I live in death Valley, very hard to keep case cool)
Soundblaster Platnium
Klipish 4.1 pro speakers.
21" Nokia
Promise ATA 100 raid PCI controler
cheap ethernet card
cable modem ( external)
Blackout buster/250 meg zip/HP phopo printer ETC.
very powerful and rated as one of the best CPU coolers ( forgot the name) with special 7200 rpm fan.


This is the change I made ( by the way, I will post all the old benchmarks vrs the new one if anyone is interested, I think at least one member already said they wanted to see them) and they are the only changes.

Replaced Abit KT7A Raid with Asus A7M266
Replaced 384 meg PC-150 with 512 megs of Samsung DDR
Replace 1.2 Gig T Bird with 1.4 T bird.
replace G force 2 with Gforce 3

Loaded the AMD mini port drivers and tried both with and without the VIA drivers ( lots of confusion on that one, book said to install)

I flashed to the current bios, I used the normal amount of paste, etc, and my CPU still runs at 51/53 at idle and 55/56 under a full load. I am only concerned because my 1.2 ran at a constant 39/40C so this is much hotter, even though it is still in range. Since I have ruled out my CPU cooler, I am stumpped as to why it would run so hot. Is the voltage supposed to be the same for the 1.2 as the 1.4 cause I did not change any of that? I would really appreciate any advice, although I have built many computers , I am still basically an idiot that feels his way around everything after crashing it a hundred times so please forgive me if this is a stupid question, I really do want and appreciate everyone's ideas. Thanks!!

One more thing, I do not think it will help with the CPU but will with the case temp ( which is also higher than it was before) but since I am just puting all this together, I have not put the sides on yet so I do not have all the big 120 MM fans blowing all over the place. I assume that it will bring down the MB temp, but I did not think it would do to much to the CPU, the heatsink is hot to the touch but maybe I am wrong and all those fans are the reason? I have not hooked them up yet since I wanted to work this out first and they are indeed a hassle to hook up but I guess I should try it just to rule it out? I though maybe someone knew or had read the 1.4 is famous for running hot, I haven't. Thanks again!!

2 things...

1) i know it can be annoying to work with socket-a coolers but did you try to reseat it? you said you put the normal amount of paste...since you are using thermal grease i assume the thermal pad (pink goo) has been removed. also, maybe the "normal amount of paste" isn't quite the right amount or the hsf isn't contacting the core well. just a thought

2) as for the big mama jama fans, i would think they will definately make a difference since you said the heatsink is hot to the touch. all those fans blowing around (assuming they don't leave dead air pockets, which i doubt with all that cfm) will remove heat from the heatsink, which in turn will remove head from the cpu. also, can you think of the name of the heatsink and fan....

That might be the right temperature difference between the two! The Tbird is a hot running chip.I believe that there are fans rated especially for 1.3ghz and above. You need to buy a new fan thats all!

Asus normally adds 10-degrees to the temperature when it reports it since the thermal sensor is under the chip and not in it. They believe by adding that amount you get a more accurate value.

You really cannot accurately compare temperature readings from two different motherboards. The Asus boards read temperatures higher than most other boards as they try to compensate for the fact that the thermal probe is not in direct contact with the core.

However, I must say being closer to the core can only mean it is more accurate.

Thanks for the help guys, I will try and plug in all the fans, button op both side, fire up all the wind machines, and see if it gets better. But I did feel the heatsink before when it was an Abit with the 1.2 and is was cool to the touch, it is not now. But I assume 55C is safe?

Easy way to compare: Put the 1.2GHz proc in your Asus motherboard and see what temp it shows; then post back the comaparative scores.
I think AMD's site says that T-birds are good to something like 65-70C.

I stuck the side on this big devil and fired up all those massive 120MM fans, CPU is now at 46, MB temp went from 40C to 29, guess the fans are doing some good after all. Since it is so hot where I live, I had to get all the air I could get moving, this case has over 750cfm and does a great job, as long as you have a powerful power supply to feed all those hungry fans!! Thanks for all the input!!
