REPAIR VS REPLACE · SINGAPORE

5 signs you need a repaste, not a new PC

A PC that feels slow or runs hot isn't automatically due for replacement. Dried thermal paste and dust buildup mimic the symptoms of ageing or failing hardware. Here are five signs it's a $128 fix, not a $1,000+ one.

Check these before you shop for a replacement

1. Fans are louder than they used to be

The same games and tasks now trigger fans to spin up harder — a sign your cooler is working overtime to shed the same amount of heat.

2. Performance drops the longer you play

Strong FPS for the first 15–20 minutes, then a noticeable dip, is a classic sign of thermal throttling, not a CPU or GPU that's "worn out".

3. It's been 2+ years since the inside was opened

Thermal paste dries out over time regardless of usage, and dust accumulates continuously in Singapore's humidity — both compound after roughly two years untouched.

4. Sudden shutdowns under heavy load only

If crashes happen specifically during demanding games or renders but the PC is stable otherwise, overheating protection kicking in is more likely than a failing part.

5. It runs fine right after a cold boot, then degrades

Good performance when everything is cool, followed by a decline as the session continues, points directly at heat build-up rather than an outdated component.

If none of these fit

If your PC runs cool and quiet but simply can't hit the frame rates or workloads you need — even right after a clean boot — that's a genuine capability gap, not a thermal issue. In that case, comparing a new custom build makes more sense than servicing an older one.

Repaste vs replace, answered.

How do I know if my PC needs a repaste instead of a full replacement?

If your PC is slow to reach normal-feeling performance until it warms up, runs noticeably hotter and louder than it used to, or throttles under sustained load despite otherwise healthy specs, these are signs a repaste and clean will likely fix it, and DreamPC's $128 Deep Clean addresses exactly this before you spend on a replacement.

Cooler teardown, fresh repaste and load testing — often all an ageing PC needs.

If a proper clean and repaste doesn't resolve the issue, or your PC genuinely can't handle the games and work you need, compare a new build instead.
