Do CPUs designed for higher speeds run hotter than slower chips?

Obviously, overclocking a chip raises its temperature significantly. So what's the temperature difference between, say, an old 700 Mhz Athlon and something new like an AthlonXP 1500? Does the faster chip run significanly hotter, or is part of the advance in the CPU production technology the ability to make it run faster at a similar temperature? The reason I'm wondering is because I'm contemplating replacing my 700 Mhz Athlon/old motherboard with a new Abit KG7 and an AthlonXP 1500 1.33 Ghz. I think I can get the new board in the old case, but the only ventilation in the case is the two power supply fans (there are no separate case fans). My old setup has always been very stable, but I'm concerned about too much heat in a new setup.
 
does your new cpu come with a fan and heatsink? typically, that's all i'd worry about.
 
I'll be applying my own fan and heatsink. I'm looking at the Thermaltake Volcano 6, which is AMD approved for up to the AthlonXP 2100 or something like that.
 
if it's AMD approved, i wouldn't worry about it if everything is properly installed....you should be good to go with the new cpu and proper cooling system....but if you are really worried about heat you could just take the top off of your case....just don't spill any beer or coffee on the pc..
 
Invariably, the more Transisters you pack into a smaller space (which is all they've been doing since Pentium's inception. There haven't been significant changes to the pentiumCPU core in 10 YEARS) the more heat is produced, so yes, faster CPU's will always run hotter .
What size Case are you talking about (Desktop, MiniTower, Full Tower?) I've Worked in MIS Department at the local Cable company since I was 17, I've built a grip of computers for various uses, and I also have been called upon to "upgrade" countless friends, and familymember's computers, so I know what I'm talking about. Many times because of changing trends and Proprietary Setups (Riser Cards for PCI Slots or just non-standard Mobo's) I end up buying a new case to house the "upgraded" system in. ( I currently have one computer that still has the OG 2x CD ROM that came with the IBM PS/2 that this beast evolved from! ) Consider getting a New Tower Case. It's not that expensive (70-130 usd), you'll have plenty of room to work in without cutting your hands up, plus you'll get more fans and open air space. I wouldn't put gigaanything into a case with just Power Supply fans! Another thing to consider are additional fans that fit into a spare PCI slot or in a free 5 1/4'' bay. they are powered from the Power Supply cables and work well to reduce internal heat. good luck!
 
I'll second Tyranny's suggestion and recommend you get a new case.

In case you can't, don't go for the TT Volcano 6. It's extremely noisy, and doesn't do a greta job of cooling the CPU down either. It's just about OK for an XP 1800 in a very well-ventilated case. You'd be better off by using a huge heatsink with a low-power fan if you want to keep it quiet (you're on a recording BBS). The thermalright AX-7 is a good choice, and with a Panaflo or Vantec 80mm fan you're looking a a very quiet and cool computer, especially that your running a relatively low-heat CPU. The XP 1500 works well with even a Volcano II, but those are very noisy heatsinks.

To answer your original question, yes the XP 1500 will be hotter than the Athlon 700. But not by much. The XPs run much cooler than the Thuderbirds, which run cooler than the Athlon 'Classic' which is what yours is. Consider using a quiet fan though. A case fan is more or less a necessity.

Huh, I don't know how I missed those replies before. Anyway, too late, I already got the Volcano 6. I've assembled the system, but I've decided I don't like where the power supply sits--right in the path of the CPU fan. With the power supply sitting on top of the chassis rather than mounted in the case and the case cover off, my CPU temp under a moderate load is around 43 degrees C. With the PSU mounted, it's around 46 degrees C. And with the cover on, it jumps to 49 degrees or so. I'm going to sell my parents my old board/processor, so I may pitch the idea of trading cases with them. Their case is plenty big, and I have more upgrades installed in my unit than them, so I'd be better off with it. And I know for a fact the old board/chip worked well in the old case.
 
Well, hold on--I just checked out some other AthlonXP users' temperature readings on this board, and most people had temps like mine. I'll mess with it some more to make sure. Maybe I'll keep my old case.
