Whenever my room temperature rises my pc starts lagging in games

[greenlover]

Hi there!

My specs:
Mobo: MSI G41M-P33 Combo
CPU: Core 2 Quad Q9650 3.00GHz with after-market cooler.
RAM: 8GB DDR3 1066MHz
GPU: Nvidia Geforce GTX 650Ti 2GB GDDR5 OC Edition 128-bit
OS: Windows 10 Pro
Case: Zalman Z11 Plus (5 fans)

Ok, now the only game I'm playing is Smite. I played Single Player games too and the problem still the same so I don't think my internet is the problem here. Please help me, I've tried every single method and solution but the problem still persists. I cleaned my pc of dust, changed my thermal paste, reinstalled windows, tried a ton of "fixes" from Youtube, updated all of my drivers. I'm so desperate right now. I've done all of these in vain. Can someone come with a real solution please? I can play games only in the evening without lag because evenings are colder. I will do anything you ask me, please help!!! I dont want to change my hardware components/upgrade my pc since this rig meet the recommended requirements. I'm playing 1-2 minutes perfectly and then it keeps lagging about 1-2 mins

Guys I think me and my friend who is IT technician, found the problem. He came by today and checked mobo temperatures (northbridge and southbridge) and my northbridge temp is just hot at the touch. He cleaned that heatsink of glue and applied some thermal paste on it. Also, he will bring to me a 80mm fan for that northbridge heatsink. I checked hwmonitor again under load and saw that tmpin1 is at 65 degrees as you see. Then I searched on forum and found this: http://www.tomshardware.co.uk/forum/id-1835129/msi-g41m-p33-combo-chipset-heat.html and I think I got the same issue. Hopefully that 80mm fan will fix my problem. Here is the hwmonitor picture under load: https://ibb.co/cP5mEx and as you see, this cpu still rocks (temps are great), northbridge is the big deal (tmpin1) and after I get my fan I will come back to tell you if my problem was solved or not. Thank you all! <3

Sounding like VRM on the motherboard then (completely missed that possibility).

Seems like geofelt was on the right lines on air and cooling. May have taken a while but hopefully that will fix it.
