Hi! Recently my helios 300 keeps getting high idle temps between 60-70 C and up to 95 C when AAA gaming. I want to try undervolting my CPU using XTU but it seems voltage offset is greyed out. I have version 2.04 bios. quick specs: i5-10300H, rtx 3060

Those areas serve two functions. They act as mounting pads and help immobilize for 'finned heat exchangers' from fan air to coolant inside the tubes to the CPU and GPU. And they help cool other chips like VRAM underneath. If the pink putty is still sticky and not dried out, you can spread it on top of the chips and re-use it. Cooling those chips is not as critical as CPU & GPU.

>>> idle temps between 60-70 C and up to 95 C when AAA gaming.>>>>Way too high at both idle and gaming! Undervolting will likely make games unplayable. When was the last time your changed the thermal paste on the CPU and GPU heatsinks? This is regular maintenance that should be done yearly if you're a heavy gamer.

Yeah, I think after 11 mos, the factory stuff might be dried out. If it was mine, I'd just use Kryonaut or ArcticMX4. Not factory paste. No pad either. I think only thin layer of paste, grease or putty is best.

Thanks for the help, man. Greatly appreciated. 😀0

Repasting didn't fix the issue. Still idling at same temperatures. btw those temps are from the cpu. the gpu seems stable. also i just found out that the process "System" in task manager keeps using up to 20% cpu and cpu speeds stay at maximum even at idle. i did a clean format. but nothing changed.0

Then I suspect the tube carrying coolant from the fan's heat exchanger to the CPU's heatsink is either blocked or broken. New modules without the fans should be about $50usd. Google search the part no for vendors who ship to your location.

Btw, about repasting. I just spread out the pea sized paste to cover the entire cpu chip in a thin layer, just enough not to see the surface of the cpu chip. Was that enough?0

No. Sorry. Don't think heat sinks are problem. Problem is the tube carrying the coolant from the fans to the cpu.

Btw, just some observation: sometimes the cpu runs cool if it was turned off overnight. Then, the high temps return if under heavy use. I also noticed that turning off boost, either through TS or adjusting cpu power in power options, the temps drop instantly. From 90°+ down to 76°.0 -

Especially if any tamper seals over screws or case seams were torn in doing this.

As with throttlestop, performance DID drop while i was playing AC origins. Haven't tried in other games, tho. Will update you soon.0 -
>>>Yeah seems i voided the warranty.>>>Then you're free to replace the thermal module yourself. You can order it on line from any vendor who ships to your location. Just google search the part nos.

>>>but heavy use still hits 96° though less frequent. it usually stays at 88 - 91 >>>Sorry. This is still way too high. There's only a limited number of times the processor will tolerate temperatures above about 94°C. Then they just stop working altogether. If it was mine, I'd replace the thermal module to reduce the chances of this happening. A lot cheaper insurance than buyng a mainboard.
