When I was adjusting my desktop settings I noticed several changes.
Hi,
I own an older desktop setup (Intel Q6600, 4 GB DDR2, 1 TB SATA HDD, 500 W SMPS).
Recently, when opening several Google Chrome windows, the CPU temperature reached 90-95 °C despite the room being 30-35 °C.
Someone suggested using underclocking and undervolting to reduce overheating.
Could you please explain step by step how to do this? I’m using Windows 7 (64 bit). Also, what are the safe temperature limits for me?
Thanks in advance.
First thing to understand is whether your motherboard can adjust CPU clock speeds and voltages, or if the CPU itself supports it. I'm skeptical about that, honestly, but I'm not very familiar with Intel. DDR2 memory indicates a fairly outdated setup. If you haven't already, I'd clean the dust from the heatsink thoroughly—unless the fan is actually running, it won't help much.
I had already cleaned the CPU and the processor heat sink fan when I opened the cabinet to re-paste the heat sink with thermal grease over the processor. I have a Gigabyte G41-m combo motherboard.
Could you let me know if there is a method to manually adjust the processor voltage and clock speed using the Windows 7 interface? Since I can't use my PC due to overheating, it's quite challenging to look up new information over the phone.
Under-volting generally follows the same techniques as over-volting and overclocking. This means the hardware, including the CPU and motherboard, must be able to handle it. From what I know, it isn't built-in to your setup. It might be feasible with some third-party software (see this discussion: https://forums. but it will be quite risky. In your case, the overheating seems linked to the changes you made to the system. Please verify your CPU cooler's attachment to the CPU carefully—make sure it's secure. Intel used plastic clips back then; check if any have come loose.
Yes, under clocking and under volting the trick worked. I adjusted the CPU multiplier to 6 (the lowest), set FSB to 266Mhz and lowered the core voltage to 1.000 v. Now even with 8-10 tabs open in Chrome, the temperature stays below 75 °C.

The main issue remains: the HDD is making intermittent noises and the PC shuts down briefly. I ran the Toshiba's HDD tester a few days ago and it passed. Could be something else? The PSU or another component?
If the HDD is producing unusual sounds and the system briefly freezes, I assure you the drive is likely defective. I rely heavily on the Toshiba test tool as much as any Toshiba drive (not at all).
Avoid using this computer except to back up your data.
Backup your files, beginning with the most critical items, since the situation could worsen quickly and full recovery may not be feasible. This advice comes from years of professional computer repair and data backup experience.
I'm curious about whether that CPU has any paste present, even under those high temperatures; it shouldn't reach 95º. The 75°C is also quite high, especially with the stock HSF combination running at 1.5GHz and 1 volt—it shouldn't hit those levels, not at all.
Make sure the heatsink is firmly attached. If the case lacks fans, consider adding some, including an intake and exhaust, even if you use 80mm fans; it will help. You might also remove the side cover if you're okay with the appearance.
Avoid using chrome on such a machine—it will always try to extract every last bit of performance, potentially overloading your memory and damaging modern builds. Opt for pale moon, seamonkey, stock chromium, or stock Firefox; none of these are significantly better than chrome anymore, just filled with unnecessary bloatware.
The hard drive making noise is a warning sign. It could mean the motor is stuck (which can be fixed easily) or it might be completely failing—hard to tell. Check CrystalDiskInfo if you enable SMART on BIOS setup; this will help display any issues.
Thank you for your reply. When the CPU reached 95 degree Celsius, I opened the stock heat sink and applied thermal grease on it. It was just two-three days ago. I tried chromium and sea monkey, but the temperature is still 71-73 degree Celsius. Please advise further. The HDD beeping and PC hanging issue seems to have disappeared after replacing the HDD SATA cable with a new one.
