Should I use thermal paste or thermal pads for my GPU?

Quick Answer

Use thermal paste on GPU cores and thermal pads only where the card originally uses pads on memory or VRM contact points. Do not replace pads with paste or guess pad thickness. The right choice is about contact, clearance, and service risk, not appearance. Budget around R150 to R350 for quality paste, more for pad sets, and about R1,400 to R3,500 for mainstream AIO cooling.

Know what each cooling part does

Paste thickness is thin and direct on the GPU die, while pads are measured in millimetres for memory and VRM contact. Wrong pad thickness can worsen temperatures even when the paste is new. Watch actual temperatures: a GPU core in the 70s Celsius can be normal, while memory hotspot readings near the limit need more careful attention. For CPUs, compare boost clocks and fan noise during a 10-minute render or game session rather than judging idle temperature only.

Avoid risky maintenance mistakes

Opening a GPU can affect warranty handling and can damage small connectors if rushed. If the card is new, noisy, or unstable, check support options before taking it apart. For CPU coolers, confirm socket support, radiator space, RAM clearance, and case airflow. A Ryzen 9-class chip deserves a cooler plan before the build starts, not after thermal throttling appears.

SA buying guidance

Choose known paste, pads, or coolers with clear specifications. Thermal Grizzly Kryonaut, Arctic MX-class paste, Corsair H100-class AIOs, and Arctic Liquid Freezer-class coolers are useful references, but compatibility still decides the purchase. Warm rooms make airflow more important, so clean dust filters and keep intake paths open before assuming the cooler is too small.

FAQ

Can I use paste instead of thermal pads on a GPU?

No. Paste is for the GPU die, while pads bridge memory and VRM gaps. Using the wrong material can cause poor contact and higher temperatures.

Is a 360mm AIO always better than a 240mm AIO?

Not always. A 360mm AIO has more radiator area, but a high-quality 240mm unit in a good case can beat a weak 360mm setup with poor fans or cramped airflow.

What temperature should worry SA gamers?

Sustained throttling, sudden shutdowns, or hotspot readings near the limit matter more than one warm reading. Compare temperatures before and after cleaning so you do not replace parts unnecessarily.
